Product details

Product Overview
The ZAZN electronic electric double seat regulating valve consists of PS series, 361 series, SKZ series linear electric actuators, and low flow resistance straight through single seat valves. (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. It has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy.
The double seat valve has the characteristics of small unbalanced force, large allowable pressure difference, and large flow capacity, and is suitable for clean medium occasions with loose leakage requirements and large pressure difference. Widely used in industries such as power, metallurgy, chemical, petroleum, environmental protection, light industry, equipment, etc.
