Three-Way Valves

Principle of Operation of Three-Way Valves

Fig. 8508-MO Three-Way Valves provide a convenient, economical means of diverting flow from one pipeline to another. They are often used in bypass arrangements in steam generating plants and process applications where they can save users thousands of dollars by eliminating conventional gate valves, bypass accessories and custom fabrications.

Fig. 8508-MO Three-Way Valves are designed to handle high pressure applications such as boiler feedwater service in steam power plants. All valves can be serviced in the field without removing them from the pipeline. Replaces two gate valves, one tee fitting, and eliminates four welded connections.
