Product features of electric straight through single seat control valve

 

ZAZP series electric straight through single seat regulating valve is composed of DKZ series straight stroke electric actuator and straight through single seat valve. It is powered by single-phase AC 220 V power supply, receives 0 ~ 10 mA or 4 ~ 20 mA DC signal, and automatically controls the opening of regulating valve to achieve continuous regulation of process parameters such as pressure, flow and liquid level of fluid in pipeline.
