Z90-24B valve actuators

Flameproof electric valve actuators Features 1. explosion-proof electric device can be directly related to the valve, closing valves, throttle valves and diaphragm supporting assembled into electric valve, but also with the second reduction gear assembly into DQB / DB electric It means, with ball valve, butterfly valve supporting component electric valves. It can accurately control instructions by opening and closing 1. Shell protection grade electric devices IP55 2. Explosion-proof electric device to work properly under the following conditions: altitude does not exceed 1000m; working environment temperature -20 ℃ ~ + 40 ℃; Relative humidity ≤95% (25 ℃); the work environment does not contain strong corrosive medium; short-time work, the time fixed for the 10min; rated voltage is: conventional, three-phase 380V (50Hz); special, three-phase 660V, 415V (50Hz, 60Hz); single-phase 220V, 110V (50Hz, 60Hz)
