'''3 Way Valve''' is a constant flow rate valve used for either mixing or diverting application. In these valves, the total flow rate remains constant. In applications where three way valves are employed, the liquid circuit will naturally split into two separate loops, constant and variable flow rate. | |||
These valves have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. They are commonly used to alternately apply pressure to an exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal. | |||
3 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. | |||
==Advantages== | |||
3 way valves are designed to handle high pressure applications such as boiler feed water 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. | |||
