Product Overview
The Wafer Type Dual Plate Check Valve is a lightweight, compact, and high-performance non-return valve designed to prevent backflow in industrial piping systems.
Its dual spring-loaded disc structure enables rapid closing, minimizes water hammer, and provides stable sealing performance.
The wafer design allows installation between various flange standards, making it ideal for water systems, HVAC, fire protection, chemical processing, industrial pipelines, and pump discharge lines.
