Three-way control valves, available in merging and diverging forms, consist of a pneumatic/electric actuator and a three-way merging or three-way diverging control valve. There are electric three-way control valves and pneumatic three-way control valves commonly used.
Valves are used to regulate, cut off, open the flow of liquids. They are widely applied in sugar industries for adjusting the flow of juice and water as well as regulating the steam pressure in the boiler.
