Vertical check valve products are widely used in petroleum, chemical, pharmaceutical, power industry and other working conditions of the pipeline.
The valve disc is positioned along the center for lifting movement, the bushing is made of special materials with good wear resistance and small friction coefficient, and the action is flexible and reliable.
Vertical check valves open or close the valve due to the medium pressure at the inlet of the pipe, overcoming the resistance of the spring. When the medium pressure at the inlet end is lower than the pressure at the outlet end, the spring pushes the spool to the valve seat to close the valve, prevent the medium from flowing back and play a check role
