Knife gate valve has the advantages of simple and compact structure, reasonable design, light and material saving, 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-2.5MPa, It works normally under the temperature of -29-550℃. Cannot be used in high pressure conditions.


    Knife gate valve: suitable for various powder and granular fluids and slurry fluids in general petrochemical and other food industries, cement and papermaking, environmental protection and other industries. 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.


    Installation and use of knife gate valve:


    1. Before installation, check the valve cavity and sealing surface and other parts, 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 that the gate can be opened flexibly;


    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 valve must be maintained regularly, and no collision or squeeze is allowed to avoid affecting the seal.
