Duplex basket strainer advantage: 

The duplex strainer 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. 

• Valves are soft-seated to provide bubble-tight closure.

• A variety of seal materials is available for use with several hard-to-handle fluids.

• 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 serviced vessel 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.
