Rosedale Duplex Filter

This filter permits continuous operation, 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.

Features

• Four separate valves, all operated simultaneously by a single lever
• Standard butterfly valve design with effective seal, low pressure drop, and low cost
• Any valve can be serviced individually without disturbing the other valves or piping
• Soft-seated valves provide bubble-tight closure
• Variety of seal materials available for hard-to-handle fluids
• Mechanical stops assure valves are completely open or closed

Pressure Balancing

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.

Actuation Options

• Remotely operated power actuators
• Automatic power actuation (triggered by pressure differential sensing)
• Air or electric actuation available
