Dual Plate Wafer Check Valve is a compact and efficient solution for preventing backflow in water, gas, oil, and other fluid systems. Designed with two spring-loaded plates, this valve offers quick response and minimal pressure loss, making it ideal for space-constrained pipelines.
The dual plate wafer check valve operates automatically when fluid flows in the forward direction, with the plates opening under pressure. When flow stops or reverses, the springs quickly push the plates closed, providing a tight seal that protects pumps, compressors, and upstream equipment.
Manufactured from cast iron, stainless steel, or carbon steel, this valve is corrosion-resistant and built for long service life. The wafer-style body allows for installation between standard flanges, making it easy to integrate into existing systems without major modifications.
Thanks to its lightweight and low-profile design, the dual plate wafer check valve is often used in HVAC, water treatment, petrochemical, and marine applications. It meets international standards such as API 594 and EN 12334 and is pressure-tested before delivery.
Whether you’re designing a new system or replacing older, bulky swing check valves, the dual plate wafer check valve offers superior performance in a compact form factor.
