Part of the transition back to the valve electric device for butterfly valves, ball valves, plug valves and damper baffle 90 ° rotation of valve. Q-in-one DQW (the DZW Denso plus two reducer) stacking. For the control valve open, close and regulation, can be remote controlled, but also on-site operation. Widely used in electric power, metallurgy, chemical, food, textile, paper, pharmaceutical, water plants and sewage treatment sector. The power of the main technical parameters: Motor for three-phase AC, 380V (special orders 660V, 440V or 220V), 50Hz (special order 60Hz); control line voltage 220V/50Hz (special order 60Hz); Remote Control voltage 24VDC. Ambient temperature: -20 - +60 ° C (special order -60 - +80 ° C) Relative temperature: ≤ 90% (25 ° C) Ordinary type and outdoor type for flammable / explosive and corrosive media spaces ; explosion proof d Ⅰ and d Ⅱ BT4 two kinds of d Ⅰ, applies to non-coal mining face; d Ⅱ BT4 used in factories, for environment II A, II Class B of T1-T4 group of explosive gas mixtures. Protection class: Outdoor and explosion-proof type is IP55 (customizable IP67). Operating system: short-time 10 minutes (can be ordered 30 minutes).
