ZAZM electronic control valve (electric sleeve control valve)
Caliber range: DN20-DN300 Pressure range: 1.6MPA-6.4MPA Applicable temperature: -40~+250 ℃ Product application: This product has a larger flow coeffic
Product details
-
The electric (ZAZM) sleeve regulating valve consists of two parts: the DKZ series linear electric actuator and the sleeve valve. Powered by a single-phase AC 220V power supply, it receives 0~10mA or 4~20mA DC signals to automatically control the opening of the regulating valve, thereby achieving continuous adjustment of process parameters such as pressure, temperature, flow rate, and liquid level. This product has a larger flow coefficient than double seat valves, allows for a larger pressure difference, has good stability, is less prone to vibration during operation, and has strong applicability. It is widely used in automatic control systems in industrial sectors such as power, metallurgy, petroleum, chemical, and light industry.
