Product Details

Description:

As an automatic valve, DIN standard vertical installation full bore flanged end cast steel spring lift check valve's main function is to prevent the media from flowing backward, to prevent the pump and drive motor from reversing, and to vent the container medium. Under the action of the fluid pressure flowing in one direction, the valve flap opens, and when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve flap act on the valve seat, thereby cutting off the flow. It mainly includes five types: DIN standard check valve, NPT check valve, raised face check valve, soft seat check valve and vertical installation check valve.
