Excalibur® Flanged Check Valves

Product by: DFT Inc.

DFT® Check Valve SOLUTIONS for Mining

Mining Pump Discharge: DFT® Excalibur® Non-slam Check Valves installed on the pump discharge prevent backflow and eliminate the water hammer associated with it. The amount of static head does not impair the action of the valve. DFT® Excalibur units are often used on applications with static heads of over 2,000 feet. The spring-assisted, in-line design of the Excalibur helps eliminate pump damage, extremely loud noises, pipe deflections, etc. caused by the water hammer

The DFT® Excalibur® Silent Check Valve is a spring-assisted, center-guided, in-line, check valve that provides reliable, low-maintenance service for a wide range of fluids and pressure/temperature combinations. The valve consists of a body, gasket, seat, spring, disc with stem, and guide bushing. Excalibur® check valves are available in a wide range of sizes and pressure ratings and in a variety of metals to meet most check valve requirements.
