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 4-20mADC or 1-5VDC input signal to operate. Its inside has servo system, no need spare servo amplifier. Key part “ controller “ adopt advanced hybrid integrated circuit, and use resin to solid-cast. After ageing treatment, moistureproof , shockproof. Positioner adjust zero , trip , sensitivity conveniently. Function switch can choice direct action, reaction, choicing stop signal three situation. Meanwhile, actuactor has overload protection, temperature protection and compressed spring protecting valve close completely. It is a high reliable product, with straight trip and angle trip consist of electric control valve.
