The vertical pure nickel check valve disc moves up and down along the center. The sealing surface has good wear resistance, small friction coefficient and other characteristics, and the action is flexible and reliable. This series of valves are normally closed. Due to the pressure of the medium at the inlet end of the pipeline, the valve is opened by overcoming the spring resistance. When the pressure of the medium at the inlet end is lower than that at the outlet end, the spring pushes the valve core towards the valve seat to close the valve, preventing the reverse flow of the medium, so it plays a check role. The valve adopts spring supported spool, which can be installed vertically or horizontally.

Vertical pure nickel check valve products are widely used in petroleum, chemical, pharmaceutical, power industry and other working conditions of the pipeline. Among similar products, there are pure nickel corrosion-resistant check valves, nickel chromium alloy corrosion-resistant check valves, nickel copper alloy corrosion-resistant check valves, nickel molybdenum alloy corrosion-resistant check valves, nickel chromium molybdenum alloy corrosion-resistant check valves, etc.
