ZDSM series straight stroke electric sleeve regulating valveDetailed product description：

The ZDSM series straight stroke electric sleeve regulating valve consists of a sleeve valve paired with a German imported PS series electric actuator. The electric actuator has a servo system inside, which does not require a separate servo amplifier. It can be controlled by an input control signal (4-20mADC or 1-5VDC) and a single-phase power supply to adjust parameters such as pressure, flow rate, temperature, and liquid level. Adopting a balanced valve plug structure, it has the characteristics of good valve plug stability, low vibration, low noise sensitivity, large allowable pressure difference, and simple wiring. It is widely used in industrial automatic control systems in industries such as power, metallurgy, petroleum, chemical, and light industry with high flow coefficient and strict leakage requirements.
