What Is a Check Valve With Spring?

Aug 25, 2022

A Check Valve with Spring is a type of check valve with an internal spring. This type of valve provides better sealing performance and does not slam during operation. The internal spring also improves the cost and application of the valve. It is generally preferred over other types of check valves. This article will provide you with some information on these valves and how to select the best one for your application. You can also find out how spring-assisted check valves differ from conventional valves.

A spring-assisted check valve is a relatively new type of internal valve mechanism. This type of valve opens when a flow passes through, then closes when the flow reverses. It is ideal for high-pressure applications, as the internal spring minimizes water hammer and can be installed in any direction. This type of valve is also highly customizable. Depending on the application, it may be used in a wide variety of pipeline configurations, including vertical ones.

Orthoplanar spring check valves can be machined or laser-cut. They can be manufactured with varying thicknesses of PET, and the spring can also have melt ridges on its edges. The main dimension of the valve housing is 10 mm, and the spring measures approximately 2.3 mm in diameter. A spring with a thicker spring will open at a higher pressure, while a thin, soft spring will leak under the same pressure.

The non-slam operation of a check valve is advantageous in a variety of applications. Its primary benefit is the prevention of water hammer, a phenomenon where the momentum behind a sudden surge of pressure reverses direction. The non-slam operation of a check valve results in less wear and a longer lifecycle. Non-slam check valves are a preferred choice for many applications, including gas pipelines, chemical processing, and gas mining.

Another type of non-slam check valve is the nozzle. These non-slam valves feature a nozzle that provides optimal control and performance. The nozzle design prevents reverse flow before it occurs. This feature sets it apart from other non-slam check valves. This type of valve is usually used for applications that involve the safe passage of high-pressure liquids.

A spring check valve is an excellent choice for the majority of applications. They are made from metal wire wound around a cylinder. Adding an internal spring to a valve can improve the sealing and immediate closing performance of a check valve, allowing it to be installed in any position. In addition, an internal spring eliminates the influence of gravity on a check valve's performance. The influence of gravity on a check valve's operation can cause it to malfunction and need to be replaced.

A spring check valve is cost-effective and available in a variety of sizes. It is typically available in a brass body or a 304 stainless steel body. Both materials feature an EPDM seal, and they have different end types and materials. Spring check valves are ideal for indoor and outdoor systems because they can withstand corrosive liquids and gases. While they are more expensive than other types of check valves, they are still an excellent choice for most applications.
