At present, the gate valves on the market have a general sealing performance, and the phenomenon of water leakage and rust is common. The soft seal gate valve overcomes this disadvantage. The soft seal gate valve achieves a good sealing effect by making use of the compensation function of the elastic wedge to produce a small amount of elastic deformation.

Common Sense of Installation and Maintenance:

1. Before installation, we should check the soft seal gate valve chamber, sealing surface and other parts, and no dirt or sand particles are allowed to attach;

2. The bolts at each connection part should be tightened evenly;

3. The packing position should be checked to ensure the sealing of the packing and the flexible opening of the wedge;

4. Before installing the valve, the valve model and connection size must be checked to ensure that they are consistent with the valve requirements;

5. When installing the valve, the space for valve actuation should be reserved first;

6. The driving device should be wired according to the circuit diagram;

7. The soft seal gate valve must be maintained regularly and shall not be collided or squeezed at will to avoid affecting the sealing.

Soft seal gate valve has the advantages of reliable sealing, good elasticity and long service life. It can be widely used as a cut-off device on the pipelines of tap water, sewage, construction, petroleum, chemical industry, food, medicine, light textile, electric power, ships, metallurgy and energy systems, etc.
