The vertical check valve opens or closes the valve due to the medium pressure at the inlet end of the pipeline 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 valve core to the valve seat to close the valve, preventing the medium from flowing back and acting as a check. Vertical check valves are widely used in chemical, liquefied petroleum gas, fluid, and other industries.
