A three-way control valve is a compact valve and actuator system designed to accurately control the flow of water, oil, steam, and other industrial fluids, making it particularly useful in heating and cooling systems. Typical applications for three-way control valves include air-handling units, water chillers, boilers, and fan coils.
The primary function of a three-way control valve is to manage fluid flow by either shutting off the flow in one pipe while opening it in another or mixing liquids from two different pipes into a single outlet. This versatility allows the valve to either separate a single flow into two different pipes or combine flows from two sources into one.
