Under the condition that the valve body, bonnet and all parts of the existing gate valve are in good condition, the valve cannot be used only if the sealing surface is slightly deformed or corroded, resulting in great waste.

Therefore, the customer hopes that the valve seat and the sealing surface of the valve plate are not easy to deform, corrosion resistant, and the vulnerable sealing materials can be replaced. The valve plate and the sealing surface should not have friction or minimize friction during opening and closing. Dervos soft seal gate valve can meet the needs of customers.

Advantages of Soft Seal Gate Valve in Application:

1. Low flow resistance. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.

2. Compared with the globe valve, opening and closing is labor-saving. Whether it is open or closed, the movement direction of the wedge is perpendicular to the medium flow direction.

3. The closing time is long and the water hammer phenomenon is not easy to occur.

4. The medium can flow in any direction on both sides, which is easy to install.

5. The structure length (i.e., the distance between the two connecting end faces of the shell) is small.

6. Simple shape, short structure length, good manufacturing process and wide application range.

7. Compact structure, smooth channel and long service life.

8. PTFE packing is used for reliable sealing. The operation is light and flexible.
