ZDLN electronic electric double seat regulating valve is composed of PS series and 3610 series straight stroke electric actuator and low flow resistance through single seat valve. (can also be equipped with other brand direct travel agencies). The electric actuator is an electronic integrated structure with servo amplifier, input control signal (4-20mADC or 1-5VDC) and power supply can control the valve opening to adjust the pressure, flow, liquid level, temperature and other parameters. It has the characteristics of sensitive action, simple connection, large volume, small volume and high adjustment precision. The control accuracy and performance are obviously improved than that of DKZ. The single seat valve is suitable for occasions where the leakage is strict, the pressure difference between the front and back of the valve is low, and there is a certain viscosity. ZDLN electronic electric double-seat regulating valve is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.
