Knife Gate Valve Used in Mining，Paper Industy And Water Treatment

  Knife gate valve is popular used in mining, paper and water treatment industy, Product Features of the knife gate valve:

  1. Valve body:

  A) Knife gate valve adopts integral structure, ultra-thin body, full flow, to avoid medium leakage and flow loss to the greatest extent, and is convenient for installation and use.

  B) Fixed guide PAWS are adopted at the bottom of the valve flow passage to fix the gate, replacing the groove design, so as to avoid the phenomenon of slag sticking caused by media accumulation when the valve is closed.

  2. Valve disc:

  A) The bottom of the gate is designed with a knife shaped arc, so the gate has a strong shearing effect on the medium and excellent sealing effect when moving.

  B) The gate is guided by PTFE point-type, which has low friction and avoids damage to the gate.

  C) The gate plate thickness can be further thickened according to the actual pipe pressure.

  3. Valve seat:

  A) The valve adopts a replaceable seat design (non-intrinsic seal). After the sealing surface is worn, the seat only needs to be replaced, which greatly facilitates the later maintenance of the valve, prolongs the service life of the valve and thus reduces the equipment cost.

  B) Replaceable seat design USES seat cover to fix and pretighten the seat. When the sealing surface of the seat is not tightly sealed, the sealing effect can be improved by adjusting the fixing screw of seat gland.

  And the double bearing design greatly reduces the torque of the valve and facilitates the opening and closing of the valve.
