Features

  • 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.
  • Stem and gate connection is secured with self-locking nuts
  • Supports integrated in the body casting protect the gate from deflecting under pressure
  • Body of ductile iron with 100-150 μm UV resistant polyester coating, RAL 5017. Optionally of acid-resistant stainless steel or duplex
  • Yokes of carbon steel with coating 100-150 μm of plascoat PPA 571 Aqua
  • Gate, stem, bolts and nuts of acid-resistant stainless steel
  • Washers under the bolts protect the coating
  • Slim design and low weight
  • Adjustable top packing gland enables sealing replacement without disassembly of the valve
  • Approved according to the 97/23/CE European Pressure Equipment Directive
  • Electric linear actuator for 24 VDC, enclosed to IP66 moving/IP69K resting
