Single Check Valve Qrc

The Stainless Steel QRC Single Check Valve is a one-way automatic shutoff valve located in the socket, primarily designed for pneumatic tool lines. It facilitates the connection of air piping in factories and air tools with hoses. Both the socket and plug are available for threaded and hose connections.

The Quick Release Coupling (Single Check Valve) is ideal for systems requiring one-sided flow and where flow sealing is essential. It provides a leak-proof connection without the need for mechanical tools, achieved simply by pressing the plug into the socket.

The Quick Disconnect Coupling (Single Check Valve) includes an unvalved plug designed to release pressurized air into the atmosphere, ensuring safe and efficient operation.
