Action principle

The valve is composed of body, cover, disc, rocker and rocker shaft and other parts, the disc can automatically prevent fluid backflow. The disc of the valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet pressure is lower than the outlet pressure, the disc will automatically close to prevent media backflow under the action of the fluid pressure difference and its own gravity.
