Duplex Strainers Large D Type 6

Large D Type Duplex strainers 6"-20"

´┐╝The (model 120) 10" - 20" N.B Duplex strainer can be used for both oil and water services.

They are available from stock in cast iron or cast steel to meet working pressure rating requirements up to 350 psig and working temperatures up to 204 Deg C (400 Deg F).

Two disc valves operated by screwed shafts provide a positive method for changeover from one chamber to the other without a shutdown in flow. The valves are sleeved and totally protected from the liquid. They operate simultaneously so that while one is being opened the other automatically closes. Valve shafts are equipped with an indicator showing which chamber is on stream. Pressure equalizing valves are provided as standard throughout the range.

Standard features

  • Hand operated.
  • No tools required for service.
