China Manufactures Brass Screw air compressor visual check valve, No Return Valve

Check Valve is named Check valve or no-return valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent the reverse flow of compressed air. Check valves are straight-through and right-angle two. Straight through check valve with threaded connection installed in the pipeline. Right angle check valve threaded connections, plate connections and flange connections in three forms. Hydraulic check valve, also known as the lock valve or pressure control valve, which is the same with the one-way valve to prevent reverse flow of oil. However, in the hydraulic circuit, when the reverse flow of the oil flow is needed, the oil pressure can be controlled and the check valve can be opened so that the oil flow can flow in both directions. Hydraulic check valve with tapered spool, so good sealing performance. When required to close the oil circuit, this valve can be used as a one-way locking oil pressure from the packing effect. Leakage check valve control oil leak-type and leakage of two types. In the reverse flow of oil flow without back pressure in the internal discharge available; otherwise need to leak, in order to reduce the control of oil pressure. Installation Check Valve Check Valve Swing Check Valve Installation position is not limited, usually installed in the horizontal pipe, but can also be installed in the vertical pipe or inclined pipe. Precautions When installing the check valve, pay special attention to the flow direction of the medium, so that the normal flow direction of the medium and the direction of the arrow indicated on the valve body should be consistent, otherwise, the normal flow of the medium will be cut off. Bottom valve should be installed at the bottom of the pump suction pipe. When the check valve is closed, water hammer pressure will be generated in the pipeline, which will cause damage to the valve, pipeline or equipment in severe cases, especially for large-diameter pipelines or high-pressure pipelines, which should attract the attention of check valve users . Non-return valve is only for preventing one-way opening and closing valve of various types of pipeline or equipment on the countercurrent of fluid medium.
