Quarter-turn Electric Actuators for ball valves and butterfly valves

详情

seal:through the process surface phosphor and plastic spraying, the uminum alloy enclosure has a very strong corrosion resistance. after the process of high precision machining center and numerical control machine then high precision seal, shell parts have the anti-corrosion and the rank can reach IP*7.

manual operation:each machine actuators are all equipped with manual wrench which can beoperated manually in the case of the accident power.

installation:the base is accorded with ISO***1 standard and can be installed in all omni-directional situation.

limit switch:electrical and mechanical double limit switches are set up inside electric actuators for the protection of valves with a double insurance.

self-locking:between high quality steel worm and aluminum bronze worm, the self-locking is designed,which can ensure that automatic valve won't reverse in any case.
