The ZHSP series electric straight through single seat regulating valve consists of a DKZ series straight stroke electric actuator and a straight through single seat valve. It is powered by a single-phase AC 220V power supply and receives 0~10mA or 4~20mA DC signals to automatically control the opening of the regulating valve, achieving continuous adjustment of process parameters such as pressure, flow rate, and liquid level of the fluid in the pipeline.

This product has the characteristics of sensitive action, convenient energy access, and rapid signal transmission. Widely used in industrial automatic control systems such as power, metallurgy, chemical, and textile industries.
