One way valve is fluid can only flow along the inlet, the inlet medium can not return, commonly known as check valve. Used to prevent reverse oil flow in hydraulic system or reverse flow of compressed air in pneumatic system. Check valve comes in straight through type and right Angle type two kinds. The direct pass check valve is installed on the pipeline with threaded connection. Right Angle check valve has three forms: threaded connection, plate connection and flange connection.

Right Angle check valve has three forms: threaded connection, plate connection and flange connection. Liquid control check valve is also known as the locking valve or pressure protection valve, which is the same as the check valve to prevent the reverse flow of oil. However, when the reverse oil flow is required in the hydraulic circuit, the oil pressure control system can be used to open the check valve, so that the oil flow can flow in both directions. The control check valve uses cone core, so the sealing performance is good. When requiring the closing of the oil circuit, this valve can be used as a one-way lock of the oil circuit to protect the pressure. The leakage modes of oil control valve are leakage type and leakage type. Internal leakage type can be used in the oil circuit of the reverse oil flow outlet without back pressure; otherwise, external leakage type shall be used to reduce the control oil pressure.
The One way valve is the check valve that is installed unrestricted, usually installed in horizontal lines, but can also be installed in vertical lines or inclined lines.
Note: When installing the check valve, special attention should be paid to the flow direction of medium. The normal flow direction of medium should be consistent with the arrow direction indicated on the valve body, otherwise the normal flow of medium will be cut off. The bottom valve shall be installed at the bottom end of the water pump suction line. When the CPVC check valve is closed, water hammer pressure will occur in the pipeline, which can cause damage to valves, pipelines or equipment, especially for large mouth lines or high pressure lines. PVC Check valves are only for one-way opening and closing valves to prevent the reverse flow of fluid medium on various pipelines or equipment.
Features: The One way valve is a direction control valve whose air flow can only flow in one direction but not in reverse. It works the same way as a hydraulic check valve. Compressed air enters from the P port, overcome the spring force and friction to open the check valve port, the compressed air flows from P to A; when the P port has no compressed air, under the spring force and port A (cavity) strength; the valve port is closed, make the airflow from A to P blocked. The One way valve should be used in situations where reverse air flow is not allowed. When the air compressor is inflated to the air tank, a PP check valve should be set 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 returning to the air compressor. One way valve is often combined with throttle valve, sequence valve and so on into one-way throttle valve, one-way sequence valve use.
