The vertical check valve is normally closed. Due to the pressure of the medium at the inlet end of the pipeline, the valve is overcome to overcome the resistance of the spring and the valve is opened. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the spool towards the valve seat to close the valve, preventing the medium from flowing back, so it acts as a check. Because the valve uses a spring to support the spool, it can be installed vertically or horizontally.
Application and Features:
The vertical check valve is strictly designed and manufactured according to the standard. The valve flap moves up and down along the center. The bush is made of special materials with good wear resistance and small friction coefficient. The action is flexible and reliable. The sealing performance is excellent.
Vertical check valve products are widely used in pipelines in various working conditions such as petroleum, chemical, pharmaceutical, and power industries.
