Electronic electric single-seat regulating valve, by 3810L(or PSL series) type straight travel electric actuator and low flow resistance through single-seat regulating valve. The electric actuator is an electronic integrated structure, with servo amplifier, input control signal (4 ~ 20mADC or 1 ~ 5VDC) and power supply to control the valve opening, the current signal into the corresponding linear displacement, and automatically control the opening of the electric single-seat regulating valve to achieve continuous adjustment of pressure, flow, liquid level, temperature and other working parameters. The electronic electric single-seat regulating valve has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment accuracy. Electronic electric single-seat regulating valve is suitable for strict leakage, low pressure difference before and after the valve and has a certain viscosity and containing a small amount of fiber medium occasions.
The electric single-seat regulating valve is a pressure balanced regulating valve. Accept the DC current signal from the regulating instrument, change the flow rate of the regulated medium, and keep the controlled process parameters at the given value. It is widely used in the production automation control of electric power, metallurgy, chemical industry, petroleum, textile, pharmaceutical, paper and other industrial sectors.
