Structural features :

1. Lift check valve has the advantages of simple structure, reliable action and convenient maintenance, which is widely used in purification equipment, petroleum, chemical, metallurgical, electric power, textile and other production processes

2. When the medium flows into the valve body from the direction indicated by the arrow of the valve body, the pressure of the medium acts on the valve disc to produce upward thrust. When the thrust of the medium is greater than the gravity of the valve disc, the valve opens. When the force of the medium pressure acting on the disc behind the valve plus the gravity of the disc itself is greater than the force of the pressure acting on the disc in front of the valve, the valve will close to prevent the medium from flowing back.

It can design and manufacture check valves with different structures and connection forms according to user's requirements, which can be used for various equipment.

Application:

through the selection of different structural forms and materials, it can be widely used in water, steam, oil, acid, alkali and other media.
