Product overview

Zdlq, X electronic electric three-way regulating valve is composed of 3810l (or PSL Series) straight stroke electronic electric actuator and three-way valve. It contains feeding and clothing function, receives unified 4-20mA or 1-5V · DC standard signal, converts the current signal into corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve continuous adjustment of process parameters such as pressure, flow, temperature and liquid level of fluid in the pipeline.

The three-way valve core structure adopts cylindrical thin-wall window and adopts side guidance of the valve core. It is used for proportional regulation or bypass regulation, especially for the regulation of fluid temperature control system of heat exchanger in petroleum industry. One three-way valve can replace two single seat valves or two seat valves, occupying small space and saving installation pipeline and cost.
