Detail
I. Characteristic
QF511 two-position three-way push-button valve is a plunger type push-button directional valve, which can achieve two functions of normally closed or normally open depending on the connection of the air circuit.
QF511 two-position three-way push-button valve mainly consists of the main body, stem, bushing, gasket, supply cap, compression spring and hand-snap ball and other components. The valve has two air source ports (P1) (P2), an output port (A), for normally closed use, P1 hole into the air, for normally open use P2 hole into the air, when the P2 hole input compressed air through the valve channel from the output port A output. Press the button to push the valve stem down, the P2 hole is closed with the output port A, and the P hole is connected with the output port A.
The valve is used in the pneumatic control system of oil drilling rigs and geological exploration drilling rigs for long-distance control and close inlet and outlet. The valve can also be used in the pneumatic system of other devices
