The Sant Dual Plate Wafer Check Valve is a compact, efficient, and reliable non-return valve designed to prevent reverse flow in pipelines. Manufactured by Sant Valves, a trusted name in industrial valve solutions, this valve is ideal for a wide range of applications including water supply, HVAC systems, chemical processing, oil & gas, and fire protection systems.
This valve features a dual plate (or double disc) design, where two spring-loaded plates pivot on a central hinge pin to allow forward flow and quickly close when flow reverses. This mechanism ensures minimal pressure drop during operation and fast response to flow changes, significantly reducing the risk of water hammer and system damage.
Constructed with a wafer-type body, the Sant Dual Plate Wafer Check Valve is lightweight and easy to install between two flanges using bolts. It saves space and weight compared to traditional swing check valves. The body is typically made from cast iron, ductile iron, carbon steel, or stainless steel, with internal components such as plates and springs made from stainless steel for corrosion resistance and durability.
