Frequently Ask Questions
It is a three-port control valve operated by a diaphragm actuator, used primarily to mix two fluid streams into one or divert one stream into two paths.
Yes. It can be equipped with a Pneumatic Positioner, Electro-Pneumatic Positioner (4–20 mA), Air Filter Regulator (AFR), Pressure Gauge, and Limit Switch Box for precise automated control.
Alis Valves manufactures and supplies 3 Way Control Valves for mixing and diverting applications, including temperature control, heat exchangers, thermic-fluid systems, steam, hot water and industrial process applications.
The valve uses a pneumatic diaphragm actuator to move the valve plug according to the control signal. This precisely controls the flow path, allowing the valve to mix or divert fluids while maintaining stable process conditions.
Selection depends on flow capacity, pressure rating, temperature, valve size, body material, trim material, actuator type, and whether the application requires mixing or diverting service.
Typical options include:
Linear
Equal Percentage
The appropriate characteristic should be selected according to the control-loop requirements.
