Electronic electric seat control valve 

 ◆ Model: ZDLN type 



















 【Products Overview】 



 ZDLN electronic electric seat control valve from the PS series and 3610 series of straight travel electric actuator and a low flow resistance through single seat valve. (Also with other brands of linear actuators). Electric actuator integrated structure for the electronic , within the servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve opening, to the pressure, flow, level, temperature and other parameters of the regulation of work. ZDLN electronic seat adjustment valve has a sensitive, simple connection, flow, volume, the adjustment accuracy. control accuracy and performance are significantly improved compared with DKZ type. Unbalanced force the valve seat, allowing the pressure big flow capacity and other characteristics, strict requirements for leaks, pressure clean, large media occasions. ZDLN seat valve is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.
