The Absolute duplex, using a single multi-ported valve operating system (patent applied for), is a better solution, and offers many benefits:

  • Four separate valves are used all operated simultaneously by a single lever.
  • Valves use the standard butterfly design,known for their effective seal, low pressure drop, and low cost.
  • Any of the valves can be serviced individually, without need to disturb the other valves or piping. Replacementsare readily available.
  • Valves are soft-seated to provide bubble-tight closure.
  • A variety of valve seal materials is available for use with a numberof hard-to-handle fluids.
  • Pressure drop is minimized because the flow path has the equivalent of only four elbows instead of the usual six.
  • Mechanical stops assure that the valves are completely open or closed.
  • A single-valve pressure balancing vent system is furnished to ease movement of the lever and to fill the just servicedvessel before use.
  • Vents in filter covers and drain ports in filter housing speed evacuation
  • and filling.
  • Remotely operated power actuators and automatic power actuation (triggered by pressure differential sensing) are offered. Air or electric actuation is best if such power is available. 
  • Available in carbon steel, 304 stainless steel, or 316 stainless steel.
  • Internal valve parts other than seals are 316 stainless steel. Four different materials can be ordered for all seals involved.
  • All baskets and mesh linings are made of stainless steel. 304 stainless will be supplied with carbon and 304 housings,316 stainless with 316 housings.
