Frequently Asked Questions

Q: What is the primary difference between a standard check valve and a silent check valve?

A silent check valve uses a spring-loaded mechanism to close the disc before the flow reverses, effectively eliminating the "slamming" noise and water hammer effect found in conventional swing check valves.

Q: Which international standards does the Wafer Type Silent Check Valve meet?

Our valves are designed and manufactured according to API 594, with flange dimensions following ASME B16.1 and EN1092, and tested per API 598 and EN12266.

Q: Can these valves be used in corrosive environments?

Yes, by selecting the Stainless Steel 304 options for the seat, disc, and spring, the valve provides excellent resistance to various corrosive media.

Q: What is the maximum size available for this specific wafer valve?

This model is available in sizes up to 12 inches (DN 300), with various options for ANSI and EN flange ratings.

Q: How does the wafer design benefit the installation process?

The wafer design allows the valve to be sandwiched between two flanges, significantly reducing the total length of the installation and simplifying the replacement process.

Q: What materials are used for the body of the valve?

Depending on the application requirements, the body is available in either Cast Iron (C.I.) or Ductile Iron (D.I.) for superior strength and durability.
