Features

  • Replaceable top packing gland enables sealing replacement without disassembly of the valve
  • The valve is self cleaning as particles will be pushed off the gate when opening the valve. For extra protection of the packing gland a scraper is available as an optional extra
  • Bi-directional, can be installed independent of the flow direction
  • Full bore with no reduction of the flow
  • Plane bottom prevents sediment from being accumulated
  • No cavity in the body and thus no risk of clogging
  • U-shaped one-piece NBR sealing between the body parts makes up for tolerances in coating and casting. It is reinforced with a steel insert to protect it from being damaged during operation.
