D8 Duplex

East Coast Filter’s Model D8 Duplex Bag Filter Assembly permits continuous operation while reducing overall operating costs. Flow can be switched back and forth between two filter vessels, allowing one side to be serviced while the other is in use.

Four separate isolation valves are 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. Replacements are readily available
Valves are soft-seated to provide bubble-tight closure
A variety of valve seal materials are available for use with a number of 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 balanced vent system is furnished to ease movement of the lever and to and to fill the just serviced vessel before use
Vents in filter covers and drain ports in filter housing speed evacuation and filling
