Product details
Brief introduction
The ZDLP electronic electric single seat regulating valve consists of PS series and 3610 series linear electric actuators, as well as a low flow resistance straight through single seat valve. (It can also be paired with other brands of direct travel actuators). The electric actuator is an electronic integrated structure with a servo amplifier inside. By inputting control signals (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled to adjust working parameters such as pressure, flow rate, liquid level, and temperature. The ZDLP electronic single seat regulating valve has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high regulation accuracy. The control accuracy and performance are significantly improved compared to the DKZ type. Single seat valves are suitable for situations with strict requirements for leakage, low pressure difference before and after the valve, and a certain viscosity. ZDLP single seat regulating valves are widely used in industries such as power, metallurgy, chemical, petroleum, environmental protection, light industry, and equipment.
