RV 止回阀
GEA check valves are open autonomously by the pressure which is exerted by the working medium upon the valve disc. They start to open at a differential pressure of 0.01 to 0.05 bar and are fully open between 0.1 and 0.2 bar. As soon as the flow is interrupted or the flow direction is reversed, the valve closes automatically. A built-in damping device makes this type of valve especially suitable in cases where capacity requirements fluctuate. GEA check valves are designed for installation in in industrial heating and refrigeration systems. They are installed on the pressure or suction side of compressors or in pipes in which only one direction of flow is intended.
