DFT WLC® Wafer Check Valves

PRODUCT DESCRIPTION

The DFT® Model WLC Wafer style Silent Check Valve is a lightweight, spring-assisted, in-line check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combinations. 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.
