The DFT® Model WLC Cast Iron Wafer style Silent Check Valve is a spring-assisted, in-line check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combinations. This check valve is cast iron and face-to-face according to MSS-SP126. The joint between the seat ring and body is sealed by the flange gasket upon installation preventing any leakage through the joint when the valve is in service.
The WLC® Cast Iron Check Valve is ideally suited for applications in water treatment, power generation, and other industries, though not recommended for gas or steam service. It will help to eliminate water hammer caused by double-door style check valves.
