When designing or upgrading your piping system, you have to consider a lot of factors. The right valve will help make sure that your water flows the way you need it to and that there are no leaks. There are many types of valves with different functions, which can make finding the right one for your project difficult. This guide will go over some common valves and help you understand how they work so you can figure out which one is best for your home or business.
Valve Selection Guide
There are three main types of valve designs: gate valves (also known as mushroom-head or plug valves), globe valves and butterfly valves (also known as quarter turn). Each design has its own unique benefits and limitations when compared with other styles within each category—but choosing between them can be difficult unless you know what factors matter most for your job!
There are many types of valves to choose from for your project. They range from simple check valves to complex ball valves, and each type has its own unique characteristics. The most important thing to remember when choosing a valve is that you should always take into account the specific application it will be used in, as well as the size and flow rate of your system.
Valves Types and Size
As we all know, there are many types of valves and there are some differences in the use scenarios. Therefore, for the majority of users, when selecting valve manufacturers, they should pay more attention to the types of products provided by the manufacturers, and select a variety of product types and cooperate well. In particular, dealers need to purchase a variety of different types of valves to ensure the purchase needs of different users.
To help guide your decision making process here’s our list of pros/cons associated with each style:
Ball Valves
Ball valves are the most common type of valve and can be found in many places, from your kitchen faucet to a sewage treatment plant. They work by moving a ball up and down to control flow through piping systems. These valves allow you to close off one side of a pipe while allowing fluid to flow through another side of that same pipe.
Ball valves are typically used where there is only one direction for fluid flow, such as when connecting an irrigation system or water heater drain line directly into a sump pump’s discharge port (see diagram). Ball valves are designed with two flanges on opposite sides—one flange has an opening where pipes fit tightly against its surface; this is called an “operating face.” The other flange has no openings; it’s referred to as an “occupying face.”
Gate Valves
A gate valve is used to stop or divert the flow of a fluid. Gate valves are often used in applications where a high flow rate is needed, and they can be used in both on/off and modulating applications.
Gate valves tend to be the most common type of valve used for industrial applications, as well as many other types of equipment. They can do this because they operate at high pressures and temperatures without leaking any fluids through them.
Globe Valves
Globe valves are used to control the flow of liquids or gases. They are available in a variety of styles, metal materials and sizes which makes them suitable for use in a wide range of applications. Globe valves come with either manual or automatic operation and can be used as on/off valves (check-valves) or for regulating flow rate such as throttling valves. Globe valves are available with either flanged ends or sockets at each end to allow easy installation into piping systems; they also feature stem packing for ensuring longer lasting performance.
-
High pressure: Globe valves designed for high pressure applications include butterfly, ball, plug and diaphragm designs with metal material options ranging from cast iron to stainless steel depending on the application requirements.
-
Temperature limits: There are many different types of globe valve styles available depending on your needs. Some examples include wafer style valves; these offer both side entry access points while still maintaining positive shutoff capabilities through internal packing design features
Check Valves
A check valve is a device that prevents backward flow of fluid in a pipeline or other flow system. A check valve has two main parts: a seat and a disc. The seat is usually made of metal, although in some cases it may be made of plastic.The disc is held in place by the pressure of the liquid inside the pipe, but it can move freely back and forth when there is no pressure on it from outside sources (such as water). When pressure from outside sources pushes against this disc, however, it acts as an obstacle to prevent backward flow through your pipeline. Check valves are used in water supply systems as well as oil and gas pipelines to ensure that contaminated water does not enter into clean drinking water systems accidentally
Butterfly Valves
Butterfly valves are a type of valve that has a disc-shaped body with two circular ports. The disc is split in half and the halves can rotate around the axis of the valve. A butterfly valve is used to control flow through pipes by allowing for only one or two connections at a time, rather than all four.
The choice of valves is a personal one that depends on your project needs. We hope this guide has helped you to make an informed decision about which type of valve best suits your needs and budget. If you still have questions or want more information, please contact our customer service department!
Choose your valve manufacturer by the material you want to use.
You’ll need to take a close look at the materials that your valve manufacturer uses. A valve manufacturer who works in alloy steel will likely be able to get you what you need, whereas one that only works with stainless steel might not be right for your project.
The material that’s right for your project depends on what type of use it may see, how much pressure is involved and how much temperature change there will be—just to name three factors. Some valves are made from alloys like brass or bronze; others are forged steel, cast iron or even plastic!
Here’s an example list of metal materials:
Stainless steel
Stainless steel is a type of steel that has a chromium content greater than 10%. This allows the steel to be highly resistant to corrosion, which means it does not rust or corrode easily. It is also ductile, malleable and magnetic.
The most common form of stainless steel are austenitic alloys, which contain up to 18% chromium and 8% nickel by weight. These alloys are used in kitchen appliances, cooking utensils and surgical instruments because they are resistant to fingerprints and scratches made by knives. They can also withstand high temperatures without losing their shape or strength.

Carbon steel
Carbon steel is a low-alloy steel that contains only elements from the iron family. Its melting point is lower than many other types of steel, making it easier to melt down. Carbon steel is used for making knives, saws and other tools because of its strength and durability. It’s also used to make other products such as gears, springs, bolts and nails.
Carbon steels come in varying degrees of hardness depending on how much carbon they contain. The type with the most carbon content will be harder than others but may also be more brittle if not tempered properly during manufacturing or use. If you need to know what kind of carbon steel your tool or product was made from before purchasing it (or if you’re just curious), there are certain ways you can tell by looking at it:

These are examples of commonly used types of steel.
-
Stainless steel: Used in cookware and other high-temperature applications.
-
Carbon steel: The most common type of steel. It is more durable than stainless, but less resistant to corrosion.
-
Copper alloy: Most commonly used for electrical wiring because it’s nonconductive and resistant to corrosion.
-
Aluminum alloy: This type of alloy has a very low coefficient of thermal expansion, meaning it doesn’t expand or contract as much as other metal materials when its temperature changes, which makes it useful for building airplanes.
-
Alloy Steel (nonferrous): A mixture that contains more than one metal such as iron and chromium producing a superior product with enhanced properties over plain carbon steels by having improved strength at elevated temperatures without losing malleability (ductility).
-
Nickel alloy: A combination mainly containing nickel together with small amounts of iron and cobalt forming hard alloys which are used especially for making armor-piercing projectiles or shells because they have good resistance against impact shock damage caused by explosion bursts from ordnance shells fired against them at high velocities during military combat operations involving armed forces fighting each other or opposing armies engaging in battles on land or sea fronts when defending themselves against enemy invasions into their own territory while seeking victory over their enemies during wartime times when war broke out between different nations fighting each other across borders separating one nation from another country where there could be no peace between two neighboring countries who continue fighting each other until one side wins due to some kind reason like religion differences between Muslims & Christians living together peacefully until someone’s death causes conflict between neighbors causing them not wanting any longer live together peacefully anymore so neighbors separated themselves into different villages henceforth causing divide amongst them which eventually led towards bloodshed among families since parents fought against children also brothers fought against sisters.
How to choose valves manufacturers?
If you really want a good quality valve for your project, then you need to choose valve manufacturers carefully.
As you are investing in a valve, then it is important to choose the right manufacturer. There are twelve main ways of doing this:
Choose the speciality valve company that provides the best service.
If you are in the market for a new valve, you want to make sure that you choose a company that will provide the best service. You will want to make sure that the company has a good reputation and is able to provide you with the best valve possible.
Choose your valve manufacturer based on how long they have been in business.
In choosing a valve manufacturer, you should look for a company that has been in the business for several years. A long history of experience is an indicator of quality, so it’s important to consider this when making your decision.
Also consider whether or not the manufacturer has a good reputation for quality and if they have been making valves consistently over time.
Choose ISO9001 certified materials and standard valves.
When you’re choosing a valve manufacturer, you’ll want to make sure that they can provide you with the metal materials and standard valves that you need. Good quality valve manufacturers will offer this service. In addition to this, it’s also important to look for ISO9001 certified materials. This is because these metal materials have been tested by an independent body and have met rigorous criteria for quality assurance.
Current valve inventory
How much inventory does the valve supplier have? This number is directly related to the time you need to receive valves and parts, which can be critical during planned outages or in emergencies. By working with valve suppliers with large inventories, you can increase the opportunities for the products you need when you need them.

Consider the cost of valve ownership
The true cost of a valve is not its purchase price, but the purchase price plus the cost of owning and maintaining or replacing the valve over time. In order to calculate the cost of ownership, you must know how long the valve will operate in the system between maintenance checks.
Maintenance costs must be calculated based not only on the cost of replacement parts, but also on labor and downtime. Note that some valves are easier to maintain than others. Some can be repaired in place; others must be removed from the process line.
When choosing valve products, we must not be greedy for small bargains and buy some cheap goods. Any product has its own production cost, and the natural cost of high-quality products will be much higher. The low price valve not only has no quality assurance, but also has many potential safety hazards or accidents in the later use process. It should be known that the professional and regular valve manufacturers have strict personnel to check the raw materials and accessories of the valves, production, acceptance and inspection. The quality and performance of valve products are the key to inspect valve manufacturers. Only by purchasing high-quality valves that are suitable for you, can you further smooth the operation and effectively avoid the existence of various potential safety hazards.
Understanding Valves In-Depth
When you design your fluid system to be as optimized as possible, it is important to select the right valve to meet your application needs. The better your understanding of each valve and its proper function, the better you will be able to make the decisions that best meet your specific needs. Work with a supplier that offers training in valve selection, identification, and troubleshooting so your team can keep up to speed and understand the latest valve innovations.
Understand the valve quality control process
The quality control process is something that all manufacturers should take seriously. Both the equipment and the product need to be of good quality during the manufacturing process in order to provide complete value for money to the customer.
Ask about the scope of maintenance services for your valves
If you are looking for a reliable supplier, one of the best deals you can get is a dedicated maintenance and repair service. A reliable supplier will also provide you with many preventive maintenance tips to keep your valves in as good a condition as new ones for a longer period of time. In addition to maintenance, sometimes repairs are required depending on the wear and tear of the product.
No matter which manufacturer wins by service, the valve manufacturer is no exception. We must find the manufacturer with good service. If there is any discomfort in the later use process and it needs to be repaired or replaced, we must first find the valve manufacturer. Avoid interference problems when using the valve.
Check for compliance with safety standards
Safety standards that are followed are important not only to the buyer, but to all workers involved in the manufacturing process. Even small oversights can lead to serious health and safety issues. You don’t want to support a manufacturer who doesn’t care about workforce safety.
The more negligent manufacturers are about industrial safety standards, the more negligent they are about orders and customers. If you want quality products, it’s best to work with a supplier that adheres to all safety regulations.
Know your needs
When selecting and purchasing valves, we should first pay attention to the quality of valves. The second problem to consider is the demand problem: because different types or models of valves have different specific functions, if an enterprise does not conduct a comprehensive analysis of its own needs when purchasing valves, then the purchased valves are not necessarily able to meet its own needs. Therefore, in order to ensure that valves suitable for working conditions can be purchased, the buyer should first analyze what type of valves he needs before selecting the valve manufacturer, and determine the type and model of valves according to his needs, so as to meet the needs of working conditions.
Your specific requirements as a customer need to be respected. Before you go out looking for a reliable manufacturer of self-acting pressure control valves, you may have a specific purpose in mind. If not, we recommend first determining the purpose and scope of the function you are looking for. Different types of valves perform different functions, and even individual valves have a range of applications that need attention.
If you sort by purpose, you will be able to make targeted orders, which will prevent you from spending too much on unnecessary things. In addition to purpose, consider how long the valve will be used each day. Understanding your needs or requirements includes the following.
- The media passing through the valve.
- The temperature and pressure of the medium.
- The response time of the valve.
- The amount of time it needs to be in continuous use.
- The compatible weight of the piping.
End connections for valves
Industrial fluid systems are designed and assembled for service valves equipped with a variety of different end connections. These may be integral pipe joints, pipe threads, pipe flanges, welded ends, etc. Although not traditionally associated with the construction of the valve, end connection selection is critical to the overall composition of the valve and its ability to maintain a leak-tight system. Make sure the end connection is appropriate for your system pressure and temperature and is properly sized. Correct end connections can simplify installation and avoid additional leak points.
Valve Delivery
Once you have considered these factors and selected the best valve for your application, ask yourself, “When do I need my valve? How many do I need?”
On-time delivery and reliable supply are as important as any other factor in keeping your fluid system running and efficient.
Conclusion
A professional valve manufacturer is able to provide valves in all kinds of metal materials, like alloy steel, stainless steel, carbon steel, forged steel and cast iron. In general, when selecting a valve manufacturer, we should not only pay attention to the qualification and evaluation of the manufacturer, but also pay attention to the type and quality of the valves provided by the valve manufacturer, and comprehensively compare their cost performance. Only in this way can we select a reliable manufacturer from many manufacturers, so as to better guarantee the selected valve products.
When selecting valve manufacturers, the above factors should be taken into account comprehensively. There are so many valve manufacturers in the market, so don’t worry. It’s a real and regular manufacturer.
Of course, there are some differences in the prices of valves sold by different valve manufacturers. For example, Yang pays attention to the R&D and design of valves, so that the quality of valves can be guaranteed and the prices are very reasonable. Therefore, When purchasing valves, the purchaser should comprehensively evaluate and analyze the valves produced by different valves manufacturers, and give priority to the valve manufacturers with high evaluation, so that they can buy satisfactory products.
Yaang has been committed to providing customers with a full range of industrial valve solutions, specializing in the production, research and development, sales and service of industrial valves.
