GLC<sup>®</sup> Cast Iron Check Valve

GLC® Cast Iron Check Valve

The DFT® model GLC® silent check valve is a spring-assisted, center-guided, non-slam, flanged check valve that provides reliable, low-maintenance service for a wide range of fluids and pressure/temperature combinations. The valve consists of a body, seat, spring, disc with stem and guide bushing. Some valves have o-ring or gasket body seals. The DFT® GLC® check valve has the advantage of minimum pressure loss with silent operation.
