Knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small size, smooth passage, small flow resistance, light weight, easy installation, easy disassembly, etc. It can work at a working pressure of 1.0MPa~ It works normally under 2.5MPa and operating temperature of -29~550℃. The gate of the knife gate valve has a shearing function, which can scrape off the adhesion on the sealing surface and automatically remove the debris. The stainless steel gate can prevent the seal leakage caused by corrosion.

Precautions for installation and use of knife gate valve:

1. Check the inside of the valve cavity and the sealing surface before installation, and no dirt or sand particles are allowed to adhere;

2. The bolts of each connection part shall be evenly tightened;

3. Check that the packing parts are required to be pressed tightly, not only to ensure the tightness of the packing, but also to ensure the flexible opening of the gate;

4. Before installing the valve, the user must check the valve model, connection size and pay attention to the flow direction of the medium to ensure consistency with the valve requirements;

5. When installing the valve, the user must reserve the necessary space for the valve drive;

6. The wiring of the drive device must be carried out according to the wiring diagram;

7. Knife gate valves must be maintained regularly, and collisions and squeezing are not allowed to avoid affecting the seal.
