Pressure Self-sealing Lift Check Valve
Introduction:
The pressure self-sealing lift check valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the valve seat is acted on by the fluid pressure and the self-weight of the valve disc. thereby cutting off the flow.
Features:
1. Self-tightening seal: The higher the pressure, the better the sealing performance.
2. The high-temperature and pressure-resistant parts are made of heat-resistant alloy steel, which has good high-temperature performance.
3. The sealing surface of valve disc and valve seat is made of alloy steel or cobalt-based hard alloy, which is wear-resistant, high-temperature resistant, corrosion-resistant, has good abrasion resistance and long service life.
4. The disc can move up and down in the valve body. When the medium flows back, the disc will be closed automatically by the pressure of the medium and the self-weight of the disc.
