Electric large-diameter regulating valve
Product details
ZDLMElectric large calibersleeveregulating valveIn addition to the general characteristics of a compact sleeve valve, it also has greater flow capacity and higher operational performance. Therefore, it is particularly suitable for production process control systems for general fluid media and high flow process conditions in industrial sectors such as chemical, petroleum, metallurgy, and power plants. This valve consists of an electric (electronic) actuator and a large-diameter sleeve valve. It has a compact structure, smooth flow channels, precise flow characteristics, wide adjustable range, and minimal valve seat leakage.
1、 Overview of ZDLM Electric Large Diameter Regulating Valve
ZDLM electricLarge caliber sleeve regulating valveComposed of PS series or 3610 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 opening of the regulating valve can be controlled to achieve the adjustment of working parameters such as pressure, flow rate, liquid level, and temperature. The ZDLM point has the characteristics of sensitive action, simple connection, high flow rate, small size, and high adjustment accuracy. The control accuracy and performance are significantly improved compared to the DKZ type.
The valve core of the electric large-diameter sleeve regulating valve is a fluid pressure balance type valve core. (取决于上下文，如"but"Electric single seat regulating valveThe valve core is of the fluid pressure imbalance type, so the electric sleeve regulating valve is more suitable for situations with large pressure differences. In some situations, it can replace electric single seat regulating valves
2、 Application of ZDLM electric large-diameter sleeve regulating valve
The ZDLM electric large-diameter sleeve regulating valve has the characteristics of good stability, low vibration, low noise, and sensitivity to temperature. The single sealed electronic sleeve regulating valve is suitable for clean media with strict leakage requirements and small pressure differences. The double sealed electric large-diameter sleeve regulating valve is suitable for clean medium applications with low leakage requirements and large pressure differentials. Small hole throttling type, can be used as a low-noise valve. Electronic electric large-diameter sleeve regulating valves are widely used in industries such as power, metallurgy, chemical, petroleum, environmental protection, light industry, and equipment.

4、Allowable pressure difference
Standard configurationElectric large-diameter sleeve regulating valveAllowing a large pressure difference, but considering the erosion of the valve plug and sleeve by the medium fluid and the noise and vibration caused by high pressure difference, when the pressure difference of the valve exceeds3MPaAt that time, corresponding process measures should be taken.
