ZRHF Electric Three-Way Control Valve

The ZRHF Electric Three-Way Control Valve consists of a PSL series or 3810 series linear-travel electric actuator and a three-way control valve body. The electric actuator features an integrated electronic structure with a built-in servo amplifier. By inputting control signals (4-20mADC or 1-5VDC) and power supply, it precisely controls valve opening to regulate process parameters such as pressure, flow rate, liquid level, and temperature. The electric three-way control valve features responsive operation, simplified wiring, high flow capacity, compact size, and high control accuracy.
