Pneumatic Check Valve

Pneumatic Check Valve is a directional control valve in which the airflow can only flow in one direction and cannot flow in the opposite direction. Its working principle is the same as hydraulic check valve. Compressed air enters from the air inlet to overcome the spring force and friction to open the Pneumatic Check Valve port, compressed air flows from P to A; when the P port has no compressed air, under the action of spring force and residual air force of A port; the valve port is in a closed state so that the flow from A to P is blocked. The Pneumatic Check Valve is used in the situation that the air flow is not allowed to flow backward, for example, when the air compressor inflates the air tank, a Pneumatic Check Valve is arranged between the air compressor and the air tank, when the air compressor stops working, the compressed air in the air tank can be prevented from flowing back to the air compressor. The Pneumatic Check Valve is often combined with throttle valve and sequence valve to form one-way throttle valve and one-way sequence valve to be used.
