Double Check Valve QRC
Working Principle
Features
Material of Construction – As Per Standards
Double check valve QRC work on Push and Pull principle. When the Adaptor is pushed to the coupler, it is accurately held by the self-locking arrangement resulting in a positive & leak proof connection. This action simultaneously opens the valve & fluid flow starts. To disconnect, pull back the sleeve of the coupler, the Adaptor ejects out and the valves shut off automatically. Valves are provided in type one way sealing & two way sealing.
- Quick Release Couplings eliminate valves and screw on fittings in many pneumatic, hydraulic and chemical systems.
- Permits easy, safe, quick & reliable connections between delivery lines, pressure hoses etc.
- Connection disconnection of fluid systems is as easy as plugging in an electric gadget.
