1. Overview of ZDLP electronic electric single-seat regulating valve
ZDLP electric single-seat regulating valve consists of PSL series and 3810L series electronic actuators and single-seat regulating valves. The power supply is 220V.AC 50Hz, and it contains a servo amplifier, a position signal generator, a position limit switch and a valve position display. It can directly accept the output (4-20mADC or 1-5VDC) of industrial control instruments or computers to control the valve opening, so as to adjust the medium pressure, flow, temperature and other purposes. At the same time, it can output (4-20mADC or 1-5VDC) valve position feedback signal.
The valve body of the single-seat regulating valve is a low-resistance straight-through single-seat upper guide structure. It has the characteristics of high precision, large flow and small leakage, and is widely used in industrial automatic control systems such as chemical industry, petroleum, light industry, power station, metallurgy, etc. that require large flow and small leakage.
The ZDLP electric single-seat regulating valve and the ZAZP electric single-seat regulating valve are only different in actuators. Users can choose according to actual working conditions.
