Wafer Type Single Disc Swing Check Valve is a compact and cost-effective solution for preventing reverse flow in pipelines. Designed with a single swing disc and wafer-type body, this check valve is ideal for applications where installation space is limited, such as in HVAC, water treatment, and industrial systems.
The wafer type single disc swing check valve operates automatically when flow enters in the forward direction. The disc swings open with minimal resistance and quickly closes when flow reverses, protecting upstream equipment from potential damage caused by backflow.
Constructed from durable ductile iron, stainless steel, or carbon steel, this valve is available with different seat materials such as EPDM, NBR, or metal seats to suit various media and temperature requirements. The wafer-style body fits easily between standard flanges, making installation and maintenance fast and efficient.
With its simple structure and low-pressure drop design, the wafer type single disc swing check valve ensures long-term performance and minimal energy loss in the system. It is suitable for both horizontal and vertical upward flow installations.
Choose our Wafer Type Single Disc Swing Check Valve for dependable, space-saving, and low-maintenance backflow protection.
