Stainless Steel Flanged Vertical Lift Check Valve

Jun 02, 2020

Vertical lift check valve: The valve opens or closes because of the pressure action of the inlet end medium in the pipeline and overcomes the spring resistance. 

When the inlet end medium pressure is lower than the outlet end, the spring pushes the spool to the valve seat to close the valve and prevent the medium from countercurrent, so it acts as a stop. 

Vertical check valves are widely used in chemical, liquefied petroleum gas, fluid and other industries.
