Find My Check Valve
DFT’s Cast Iron GLC® Check Valve offers minimum pressure loss performance along with silent operation. This non-slam valve is center-guided, spring-assisted, and is capable of handling a wide range of temperature/pressure combinations along with a variety of system fluids. Each valve is constructed with a body, seat, spring, disc with stem and guide bushing, and specific models are available with O-ring or gasket body seals.

As its name implies, cast iron is the material used to create the body of the GLC® Silent Check Valve, and either bronze or 316 stainless steel is available for the trim. The valve is made with a one-piece body and “short” face-to-face dimensions. Depending on the application, both horizontal and vertical installation is possible. Not recommended for gas or steam service.
