Intelligent explosion-proof valve electric device

DZW20-18ZIntelligent explosion-proof valve electric deviceSuitable for controlling the opening and closing of valves, on-site and remote operation adjustment, bus control, etc., it is a driving device for centralized and automatic control of valves and dampers. Suitable for gate valves, globe valves, throttle valves, diaphragm valves, plunger valves, water gate valves, etc., it can also be used for 90 degree rotary valves such as ball valves, butterfly valves, dampers, etc. when equipped with deceleration worm gears. This product has the characteristics of comprehensive functionality, control system, reliable performance, easy use and maintenance, and small size. It has been widely praised and applied in industries such as power, steel, petrochemicals, metallurgy, water treatment, and papermaking.

DZW20-18ZIntelligent explosion-proof valve electric deviceCharacteristics and parameters

1. The device is dustproof, rainproof, and corrosion-resistant, with a protection level of IP55 (special orders IP65, IP67).

2. The torque control mechanism is reliable in action, easy to adjust, and has high torque repeatability accuracy.

3. 2 to 4 micro switches can be installed for opening and closing directions (special order).

4. Adopting a valve electric device three-phase asynchronous motor, it has the characteristics of high starting torque, low rotational inertia, long service life, and F-class insulation.

5. The work schedule is short 10 minutes (30 minutes for special orders).

6. Equipped with mechanical (conventional type) or LCD (conventional type without) valve position indicator, which can intuitively know the opening size of the valve.

7. Adopting a semi-automatic hand electric switching mechanism, the handle needs to be switched manually, and it automatically resets when powered. The structure is simple, reliable, and easy to operate. In the event of a power outage, the manual function can still be used to open, close, or adjust the valve.

8. There are dual protections such as travel limit and over torque limit, ensuring the safe use of the driving device and valve.

9. Power supply: Typically 380V (± 10%), 50Hz (special orders for three-phase 660V, 415V, single-phase 220V, 60Hz)

10. Explosion proof mark: ExdIIBT4 (conventional type not explosion-proof).

11. Relative humidity of the environment: ≤ 95% (at 25 ℃).

12. Environmental temperature: -20~+60 ℃ (special orders -40~+100 ℃)
