GSD

Full Round Port, Air Compressed Tube, Maximum Economy, Inherently Fail Open Design, Compact/Light Weight Design, Double Thick Sleeve Wall for Extended Sleeve Life

  • The GSD is the same valve as the GSF except it has a double thick rubber sleeve.
  • Clog resistant full round opening
  • Low pressure drop
  • No packing
  • Drop tight closure
  • Simple operation, rubber sleeve is the only moving part

Applications: Ideal for abrasive, viscous and corrosive fluids including wastewater, mine slurries, chemicals, cement, pulp stock, powder and pellets.

Operation: The GSF consists of a rubber sleeve inside a full round cast iron bonnet assembly. Injecting compressed air into the bonnet assembly causes the rubber sleeve to collapse, blocking flow through the valve.
