DZW30-24-A00-WK electric valve head, DZW overall electric device is an electric valve drive means for controlling the valve opening and closing. DZW Series multi-turn electric devices used in gate valve, globe valve, throttle valve, diaphragm valve. It can accurately control instructions by action, is for all kinds of valves, dampers to achieve remote control, centralized control of the essential drive and automatic control. The series is not only used in power plants, can also be used in petrochemical, metallurgy, and other public utilities. Body models DZW5-12-A00-WK / DZW5-18-A00-WK / DZW10-18-A00-WK / DZW10-24-A00-WK / DZW10-36-A00-WK / DZW15-18-A00-WK / DZW15-24-A00-WK / DZW15-36-A00-WK / DZW20-18-A00-WK / DZW20-24-A00-WK / DZW20-36-A00-WK / DZW30-18-A00-WK / DZW30 -24-A00-WK / DZW30-36-A00-WK / DZW45-24-A00-WK / DZW45-36-A00-WK / DZW60-24-A00-WK / DZW60-36-A00-WK / DZW90-18 -A00-WK / DZW90-24-A00-WK / DZW120-18-A00-WK / DZW120-24-A00-WK / DZW180-18-A00-WK / DZW180-24-A00-WK / DZW-250-18 -A00-WK / DZW250-24-A00-WK / DZW300-18-A00-WK / DZW300-24-A00-WK / DZW500-18-A00-WK / DZW500-24-A00-WK / DZW800-18-A00 -WK / DZW800-24-A00-WK / DZW1000-18 like. Work environment and main technical parameters 1 Power: conventional, three-phase 380V (50Hz) special, three-phase 660V, 415V (50Hz, 60Hz); single-phase 220V, 110V (50Hz, 60Hz) 2 Working environment: 2.1 Ambient temperature: -20 ~ + 60 ℃ (special order -40 ~ + 80 ℃). 2.2 Relative humidity: ≤95% (25 ℃ when). 2.3 Protection type: outdoor type for non-flammable, non-corrosive and explosive places media. Flameproof products dⅠ and dⅡBT4 two kinds, dⅠ applicable to non-coal mining face; dⅡBT4 used in factories, for environmental as ⅡA, gas mixture characteristic ⅡB grade T1 ~ T4 group: 1, all Chinese display: one multi-turn actuator Windows lcd digital high-definition, full Chinese and identifiers LCD screen. 2, phase sequence automatically correct: rotary actuators to be set free, but also free to correct power supply phase sequence. 3, the lack of protection: a power phase protection. 4, the control mode: 4 ~ 20ma signal provides feedback (provide special volume control). Remote control signal, the feedback signals are electrically isolated from the interior. 5. ban move delay protection: to avoid or reduce the mechanical part of the reaction force due to the inertia bear. This protection applies to both on-site and remote control control control. 6, electronic interlocking protection: When an instruction is being executed and remains valid, then applied another reverse control instruction (ie, the existence of two instructions simultaneously and effectively), then the electric actuator will stop after execution of the first instruction then execute the next instruction. 7, transient over-torque protection: When turned on or off to the moment when the moment was the top open, the valve will not stop the action, even after instant torque switch to open the top is closed, the valve still will not move, only to reverse the action a bit, you can lift over torque protection. 8, live remote control switch: Live remote control can be switched freely, allowing users to debug, maintain convenient. dzw / z intelligent integration of multi-turn electric switching device is a drive electric valve to control the valve opening and closing.
