Three Way Control Valve

Three way control valve with Pneumatic actuator

A type of globe valve that has three pipeline connections to provide general converging (flow-mixing) or diverging (flowsplitting) service. Variations include cage-, port-, and stemguided designs, selected for high-temperature service, and end connections can be specified to mate with most piping schemes.

Actuator selection demands careful consideration, particularly for constructions with an unbalanced valve plug.

Description

Applications that use 3-Way Control Valves

  1. The primary function, 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.
  2. 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.
  3. 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.
