  • GLC® Cast Iron Body Check Valves

    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.
