Description

The 316 Stainless Steel Wafer Type Spring Check Valve is designed for efficient backflow prevention in compact pipeline systems. Its wafer-style body allows for easy installation between flanges, providing a space-saving solution without compromising flow capacity or durability.

Manufactured from ASTM A351 CF8M (316 stainless steel), this valve offers excellent corrosion resistance and long service life, even in aggressive or high-pressure environments. The spring-assisted disc ensures fast, positive closure to prevent reverse flow — ideal for both horizontal and vertical installations.

Rated to 40 Bar (580 PSI), the valve is suitable for a wide range of industrial applications, including water, air, oil, gas, and chemical services.

What is the purpose of a wafer type swing check valve?

A wafer type swing check valve is designed to allow fluid to flow in one direction while automatically preventing reverse flow. Its compact wafer design allows installation between flanges, saving space in tight pipeline layouts, while maintaining reliable non-return performance.

How does the spring-loaded disc work?

The spring-assisted disc ensures quick and positive closure whenever flow stops or reverses. This fast action reduces the risk of water hammer, protects pumps and equipment, and ensures consistent performance even in high-pressure systems.

Why is 316 stainless steel used in construction?

316 stainless steel provides excellent corrosion resistance, high mechanical strength, and long-term durability. It is well suited for aggressive environments and can handle water, air, oil, gas, and various chemical services without compromising performance.

What does the 40 Bar (580 PSI) pressure rating mean?

The 40 Bar rating indicates that the valve is designed for high-pressure service up to 580 PSI, making it suitable for demanding industrial applications where reliability under pressure is critical.

Can wafer type swing check valves be installed in different orientations?

Yes. The wafer type design allows installation in both horizontal and vertical pipelines, provided the flow direction aligns with the disc’s operation. This versatility makes it suitable for a wide range of piping layouts and industrial systems.
