Double Check Valve Qrc

The Q.R.C. Double Check Valve is available in sizes from ⅛ inch to 2 inches. It is as easy to connect and disconnect the fluid system as it is to plug an electrical device into a socket. These valves operate on a push-and-pull mechanism. When the adaptor of the Double Check Valve Quick Release Coupling connects to the coupler, it is secured by a self-locking arrangement, ensuring an accurate and leak-proof connection. This action simultaneously opens the valves, allowing fluid flow to begin. To disconnect the valve, the coupler’s sleeve is pulled back.

Quick Disconnect Couplings with Double Check Valves feature both one-way and two-way sealing mechanisms. The attached hose does not twist during operation. These valves are widely used in hydraulic lines, vacuum systems, steam, gas, and liquid applications. We are also a leading pressure gauge manufacturers.

FAQ

A double check valve is a mechanical device that prevents the reverse flow of fluids (such as water, gas, or chemicals) in a pipeline. It consists of two internal check valves arranged in series to provide double protection against backflow.

When fluid flows in the intended direction, the pressure opens the two check valves, allowing flow. If reverse flow occurs, the check valves close, preventing fluid from moving backward.
