Overview
This series of valves are normally closed. Due to the pressure of the medium at the inlet end of the pipeline, the valve is opened by overcoming the spring resistance. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve core to the valve seat to close the valve and prevent the medium from countercurrent, so it plays a check role.
Installation method:
The valve adopts spring to support the valve core, so it can be installed vertically or horizontally.
Application:
through the selection of different structural forms and materials, it can be widely used in water, steam, oil, acid, alkali and other media.
