3810 Electric Actuator

3810, 3410 series electronic type electric actuator, using 220V AC single-phase power as drive power, that is a safety electric actuator accepting computer controller or operator 4 -20 ADC or 1-5VDC input signal to operate. Its inside has a servo system, no need spare servo amplifier. Key part “ controller “ adopt advanced hybrid integrated circuit, and use resin to solid-cast.

After aging treatment, moistureproof, shockproof. Positioner adjusts zero, trip, sensitivity conveniently. Function switch can choose direct action, reaction, choice stop signal three situations. Meanwhile, the actuator has overload protection, temperature protection, and a compressed spring protecting valve close completely. It is a highly reliable product, with the straight trip and angle trip consist of the electric control valve.

Connection size for the yoke of linear actuator

Supporting yoke parameter

Each specification actuator can be supported 2“3 kinds york connected with national unify flexible control valve. It still needs to test the actuator output force to confirm if it can satisfy the max force of the valve on and off.
