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.

QUALITY CONTORL
Each AVLOK Coupling manufactured goes through stringent quality control, right from the procurement of raw material upto final stage.
PRECAUTION :
- Avoid connecting or disconnecting a coupling under pressure.
- Residual pressure in a coupling may make it difficult to connect. In such a case, do not strike the valve end to depressurize it.
- Improper selection of seal rubber may cause leakage.
- Dust or flaws in the seal may cause leakage.
- Improper selection or improper use of the products can cause personal injury and property damage.
