  • Structural characteristics and selection techniques of direct-flow globe valve, angle globe valve and plunger valve

    Due to the low friction between the sealing surfaces during the opening and closing process, the shut-off valve is relatively durable and has a small opening height. It is not only suitable for medium and low pressure, but also suitable for high pressure media. Relying on the pressure of the v...

  • The characteristics of Vertical check valve

    Overcoming the spring resistance makes the valve open or close. When the medium pressure at the inlet end is lower than the inlet end, the vertical check valve: due to the pressure of the medium at the inlet end of the pipeline. The spring pushes the valve core to the valve seat to close the ...
