Dual slimline ball non return valves (DSFFV) from Dual Valves Australasia

Dual Valves Australasia‘s dual slimline ball non return valves feature a unique design that utilises a reinforced urethane ball to ensure dropless sealing.

This reinforced urethane ball is the heart of these vales. When the pump is in operation, the ball lifts completely out of the liquid without any interference. As the pump stops, the heavy ball falls into the seat, ensuring dropless sealing.

Available in sizes ranging from 80 to 600mm, with different sizes available on request, these non return valves offer operating pressures of up to 100 bar.

They are suitable for use in a range of applications, including:

  • mining and mineral processing
  • power generation
  • sand and gravel
  • chemical and soda ash
  • pulp and paper; and
  • environmental and effluent.
