Spring-assisted, center guided 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.
