Knife Gate Valve

- China
Main Feature:
The sealing surface can only be sealed by relying on the medium pressure, that is, the sealing surface of the ram is pressed to the seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on external forces to force the gate to the seat to ensure the tightness of the sealing surface. This type of valve should generally be installed vertically in the pipeline.

product features:
1. Valve control can be local and remote control, and remote position display and remote centralized control can also be achieved according to user requirements.
2. Light weight: the body is made of carbon steel, the weight is reduced by about 20%-30% compared with the traditional gate valve, and the installation and maintenance are convenient.
3. The use of the valve can improve the closing and sealing performance of the transmission pipeline system, minimize leakage, improve production efficiency, and protect the environment will play a positive role in promoting.
4. The sealing surface is made of high wear-resistant and corrosion-resistant ceramic material, with Mosaic technology, high corrosion resistance and good wear resistance, so that the valve has a long life and the cost performance is 10 times higher than that of ordinary valves.
