Product Introduction

The ZQSF (H) type straight stroke diversion and merging electric control valve consists of a three-way diversion and merging valve equipped with QS series straight stroke electric actuators. 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.
