Vertical Flange Check Valve

Product overview

Vertical flange check valve is normally closed. Due to the pressure of the medium at the inlet end of the pipeline, it overcomes the spring resistance and makes the valve open. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve core to the valve seat and makes the valve close, thus preventing the reverse flow of medium, so it plays a check role. Since the valve core is supported by spring, it can be installed vertically or horizontally. It is widely used in the pipeline of petroleum, chemical, pharmaceutical and electric power industries.
