Imported lift check valve

The lift check valve provided by Viti Industry features a simple structure, reliable operation and convenient maintenance. Except for the valve disc which can be freely raised and lowered, the rest of the valve is similar to a stop valve. The fluid pressure lifts the valve disc from the sealing surface of the valve seat, and the medium flows back, causing the valve disc to fall back onto the valve seat and cut off the flow.

Design features of the lift check valve provided by Viti Industry:

1. The lifting type steel stop return valve has the advantages of simple structure, reliable operation and convenient maintenance.

2. When the medium flows from the arrow on the valve body to the valve body, the pressure of the medium acts on the valve disc to generate an upward thrust. When the medium thrust is greater than the weight of the valve disc, the valve opens.

When the force exerted by the pressure of the medium after the valve on the valve disc plus the weight of the valve disc itself is greater than the force exerted by the pressure before the valve on the valve disc, the valve closes to prevent the backflow of the medium.

4. The disc of the lift check valve is located on the sealing surface of the valve seat on the valve body.

Five, except for the valve disc which can be freely raised and lowered, the rest of the part is like a stop valve. The fluid pressure lifts the valve disc from the sealing surface of the valve seat. The backflow of the medium causes the valve disc to fall back onto the valve seat and cut off the flow.
