Product Description
The function of the dual plates check valve is to only allow the medium to flow in one direction and prevent the flow in one direction. Usually this kind of valve works automatically. Under the action of the fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve flap act on the valve seat, thereby cutting off the flow.
Structural Features of Wafer Butterfly Check Valve:
- The structure length is short, and its structure length is only 1/4 to 1/8 of the traditional flange check valve;
- Small size and light weight, its weight is only 1/4 to 1/20 of traditional flange check valve;
- The valve flap closes quickly and the water hammer pressure is small;
- Both horizontal pipes and vertical pipes can be used, and the installation is convenient;
- The flow channel is unobstructed and the fluid resistance is small;
- Sensitive action and good sealing performance;
- The valve clack stroke is short, and the impact force of closing the valve is small;
- The overall structure, simple and compact, beautiful appearance;
- Long service life and high reliability.
