Applications that use 3-Way Control Valves
- Jul 24, 2018 -

The primary function of the 3-way valve is to control the amount of hot and cold water being sent through a system, which, in turn, helps in the temperature regulation and control of surfaces. A common application which utilizes the 3-way valve is in radiator systems. In this case, the 3-way valve is used to control the output temperature of the radiator by increasing or decreasing the amount of cold water pumped into the radiator unit.

Another, albeit, more surprising application for the 3-way valve is in the use of floor heating and cooling systems. The 3-way control valve will control the emitting temperature by allowing a specific mixture of both hot and cold water, which will then dictate the temperature of the floor.


There is no doubt that valves are one of the most important, yet overlooked, components in many industrial and residential applications. The 3-way valve is perfect for controlling the flow of three separate fluid lines, which allows it to regulate temperatures efficiently. The 3-way valve can shut off one pipe while allowing another to open, which can change the temperature of the fluid being output.

Also, the 3-way valve can be used to mix varying levels of hot and cold fluids by letting specific amounts of each fluid come together, thus changing the overall temperature. Some applications utilize 3-way valves, and one of the most popular is in radiator systems. Also, the 3-way valve is used in controlling the temperature of flooring systems. To accomplish this, the valve is usually paired with an actuator which is connected to a controller, and this will tell the valve when to open and close. With its many uses, there is no doubt that the 3-way valve is here to stay.
