DIN JIS 10K ANSI Gost Cast Steel Flange Pneumatic Knife Gate Valve

COVNA HK59-D-D Pneumatic knife gate valve is driven by compressed air. Pneumatic knife gate valve is simply to use pneumatic actuator to control the valve, so as to achieve the opening and closing of the valve. It can be divided into two parts: upper part is pneumatic actuator and lower part is valve. The pneumatic knife gate valve should be installed horizontally in the pipeline. The opening and closing parts of the pneumatic knife gate valve are the gate, the movement direction of the gate is perpendicular to the direction of the fluid, and the manual knife gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled.

  • Model: HK59-D-D
  • Size Range: 2''~80''
  • Pressure Range: 1.0MPa to 2.5MPa
  • Material: Cast Iron

COVNA HK59-D-D Air Operated Knife Gate Valve

The pneumatic knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and so on. It can work normally under the working pressure of 1.0mpa-2.5mpa and operating temperature of – 29-650 ℃. The gate of knife gate valve has the function of shearing, which can scrape off the adhesive on the sealing surface and automatically remove the sundries. The stainless steel gate valve can prevent the sealing leakage caused by corrosion
