Product Detail

Valve Description

The electric 3-way control valve is composed of an electric actuator and a 3-way control valve body. It has two structural types: 3-way diverging valve and 3-way converging valve. It is suitable for proportioning regulation or bypass regulation. For example, it is used for fluid temperature regulation on heat exchangers, dividing one inlet fluid into two outlet fluids, or combining two inlet fluids into one outlet fluid. The control system composed of electric 3-way control valves features simple structure, economy, stable and reliable performance.
