Knife Gate Valves Collection

Knife gate valves are stainless steel gate valves that have a sharp cutting tool installed to deal with viscous, heavy liquids, or other abrasive media. Their straightforward design and easy-to-manipulate valve setup are ideal for wastewater treatment plants, cement plants, and mining facilities, to name a few.

With dedicated workshops and superior mold casting capabilities, DomBor is sure to meet your knife gate valve needs. Carefully selected materials and contemporary design make our knife gate valves highly resistant to acid and corrosion brought by the viscous materials. The steel blade that cuts through the solid or heavy materials is specifically manufactured to retain its sharp edge for an extended period.

Highlights

  • Easily automated for on/off applications
  • One-piece body
  • Position Indicator
  • Standard wafer and lug design
  • Knife gate has a strong shear force

Main Features of the Product

  • Easily and quickly switch between manual and pneumatic
  • Knife gate valve adopts integral structure, ultra-thin valve body, full diameter flow channel. To a large extent, it can avoid medium leakage, flow loss, cost saving, and easy to install and use.
  • The valve adopts the design of replaceable seat (non-native seal). Only the seat needs to be replaced after the sealing surface is worn, which facilitates the later maintenance of the valve and prolongs the service time of the whole valve, thus reducing the equipment cost of customers
  • The bottom of the ram is designed with a knife shaped arc, so the ram has a strong shearing effect on the medium and excellent sealing effect when it moves. It is especially suitable for the control of pulp and media containing fiber
  • The double bearing design reduces the torque of the valve and facilitates the opening and closing of the valve.
  • The bracket is made of stainless steel instead of chrome plated carbon steel, with longer service life
