Electronic electric three-way regulating valve, by 3810L type (or PSL series) straight travel electronic electric actuator and three-way valve, including feeding function. Accept the unified 4-20mA or 1-5V·DC standard signal, the current signal is transformed into the corresponding linear displacement, and the opening of the regulating valve is automatically controlled to achieve continuous adjustment of the process parameters such as pressure, flow, temperature and liquid level of the fluid in the pipeline.
Three-way valve spool structure adopts cylindrical thin-wall window, and adopts spool side guide. Applied to proportional regulation or bypass regulation, especially for the adjustment of the fluid temperature control system of the heat exchanger in the petroleum industry, a three-way valve can replace two single-seat valves or two-seat valves, accounting for small space volume, saving the installation of pipelines and costs.
Electric three-way regulating valve is a kind of fluid control equipment, through the electric actuator to drive the valve core to move, to achieve the flow, pressure, temperature and other parameters of the fluid medium adjustment and control. It has the advantages of simple structure, high adjustment precision, good stability and easy operation, and is widely used in chemical industry, petroleum, electric power, metallurgy and other industrial fields.
