  • GLC® Flanged Check Valves
The DFT® Model GLC® Silent Check Valve is a spring-assisted, center guided, in-line, 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 body or gasket seals. The DFT® GLC® check valve has the advantage of minimum pressure loss with silent, non-slam operation.
