Single Check Valve Quick Release Coupling

TYPE-SC is most popular type coupler used to connect air piping in factories and used to connect air tools with hoses etc. Both socket and plug have hose use and screw use advantages. There is also a variety of other types. The types 20, 30, 40, and Types 400and600are completely interchangeable. With one check valve built into the coupling only whereas plugs do not have any check valves. Can be advantageously used where one side of the flow system needs to be sealed on disconnection.

When plug & Socket are separated


When the outside sleeve at the socket side is pulled back, the plug and the socket are separated and the socket side is automatically closed so that the fluid does not flow to the outside.
When plug & Socket are connected

When the outside sleeve at the socket side is pulled back and the socket is fitted to the plug, the valve at the socket side is automatically opened and the fluid flows.

   Handling Precautions
    (1) Always insure the direction of fluid flow is from the socket side (valve) to the plug side.
    (2) When used with jet chisel or other vibrating tools, connect a rubber hose about 30 cm long between the tool and the           coupler.
