1. It has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy. The control accuracy and performance are significantly improved compared to the DKZ type.
2. Suitable for situations with strict requirements for leakage, low pressure difference before and after the valve, and certain viscosity. Widely used in industries such as power, metallurgy, chemical, petroleum, environmental protection, light industry, equipment, etc.
3. 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.
