The characteristics, structure and working principle of the knife gate valve

The characteristics of the knife gate valve

1 it can promote the disc sealing surface and it can shave their sticky substance on the surface of the seal, automatically removes the debris;

2 With shut off on or off the throttle of dual function;

3 ultrashort structure length, saving material, reducing pipeline's whole system weight;

4 taking up small space. It can effectively support the pipeline strength and reduce pipeline vibration;

5. The triangle bracket save raw materials, to guarantee the need of mechanical properties;

6 the body guide block ram right movement. Squeeze the faster ram ensure effective seal;

7 suitable for arbitrary angle on pipe in different configuration.
