The 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, which includes a servo amplifier, position signal generator, position limit switch, and valve position display. It can directly accept the output of industrial control instruments or computers (4-20mADC or 1-5VDC) for valve opening control, achieving the purpose of regulating medium pressure, flow rate, temperature, etc. At the same time, it can output valve position feedback signals (4-20mADC or 1-5VDC).
The valve body of the ZDLP electric single seat regulating valve is a low resistance flow through single seat upper guide structure. It has the characteristics of high precision, large flow rate, and small leakage, and is widely used in industrial automation systems such as chemical, petroleum, light industry, power plants, metallurgy, etc. that require large flow rate and small leakage rate.
