Insamcor MH

A product designed & developed for harsh, abrasive & corrosive environments


DFC’s Purpose is to solve typical and perennial valve problems. We achieve this by proving quality valves that provide the lowest cost of ownership and operation, highest reliability and minimum lifetime maintenance.

DFC’s Insamcor range of high pressure ductile iron mono flanged knife gate valves feature a unique moulded body seal including both transverse and stuffing box sealing to atmosphere. The moulded seal ensures no seat pockets or cavities providing trouble free operation in high pressure applications.

Cast iron body, either FBE coated or soft rubber Lined with an added option of wear cones

Optional actuation:  hand wheel, manual gearbox, pneumatic, hydraulic and electric

Optional accessories:  proximity switches, solenoid valve, junction box

  • Mechanically retained moulded body seal
  • 230 psi CWP (16 bar) pressure rating for all sizes
  • Combination transverse seal and adjustable stuffing box and gland design ensures leak-proof sealing to atmosphere and allows maintenance and seal re-packing under full line pressure
  • Gate guided through full length of the stroke
  • Self-cleaning flush out corners prevent deposit build-up in sealing area
  • Full bore unrestricted flow area – no seat pockets or cavities
  • Bi-directional leak-proof sealing
  • Built in PTFE scrapers keep the blade free from any foreign matter over the whole width of the blade during operation.
  • Pillar design allows for easy mounting of proximity and limit switches
  • The mounting plate is designed to accept manual, pneumatic or electric actuation
