3810L straight trip electronic electric actuator is 220V AC single-phase power and 380V three-phase AC power supply two drive models of the power, accept from the regulator control signals (DC4 ~ 20mA or room DC1 ~ 5V), scheduled reciprocating motion a new type of actuator. This series actuators are used to adjust the valve actuator, almost with a variety of actions required transformation function, and valve opening signal function of the control valve and manual functions. Therefore, power generation, metallurgy, petrochemical, light industry and environmental protection should be in the industrial sector.
