Vertical flange check valve

Overview:

Vertical check valves open or close the valve by overcoming the resistance of the spring due to the pressure of the medium at the inlet end of the pipeline. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve core towards the valve seat, closing the valve and preventing the medium from flowing back. Therefore, it serves as a check valve. Vertical check valves are widely used in industries such as chemical engineering, liquefied petroleum gas, and fluids.
