VALVE

  The purpose of using a   check valve   is to prevent reverse flow of the medium, and a check valve is generally installed at the outlet of the pump. In addition, a check valve should also be installed at the outlet of the compressor. In short, in order to prevent reverse flow of the medium, check valves should be installed on equipment, devices, or pipelines. Generally, vertical lift check valves are used on horizontal pipelines with a nominal diameter of 50mm. The straight lift check valve can be installed on both horizontal and vertical pipelines. The bottom valve is generally only installed on the vertical pipeline at the pump inlet, and the medium flows from bottom to top. The swing check valve can be made with a high working pressure, with a PN of up to 42MPa, and a DN of up to 2000mm. According to the different materials of the shell and sealing components, it can be suitable for any working medium and any working temperature range. The medium is water, steam, gas...
