ZDSF (H) type straight stroke diversion and merging electric regulating valve
1、 Product Details
Product Model: ZDSF (H)
Product Name: Straight stroke diversion and merging electric regulating valve
The ZDSF (H) type straight stroke diversion and merging electric control valve consists of a three-way diversion and merging valve equipped with a German imported PS series straight stroke 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. It adopts a balanced valve plug structure, which has the characteristics of good valve plug stability, low vibration, low noise, 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 environmental protection with high flow coefficient and strict leakage requirements.
