Performance Feature
Shell--The shell is made of aluminium alloy, with anodic oxidation treatment and polyester powder coating. It is
strong corrosion-resisting and enclosure IP67,NEMA 4 and 6, IP68 is optional.
Motor--
Fully enclosed squirrel-cage asynchronous motor, small, large torque, and small inertia force, F-class insulation
rating, with termal protection to avoid damaging.
Manual Structure--The design of handle is safe,reliable,labor~saving,small.If power failure, operated by handle.
Indicator--Install indicator in the center shaft and adopts convex mirror design, no cumulate water, more convenient to observe.
Space heater--It is used for controlling temperature to avoid condensing internal of housing and keep dry.
Sealing--
Well sealing performance and enclosure IP67,IP68 is optional.
Limit switch--Mechanical, electronic double limit. Mechanical limit stopper are adjustable, safe and reliable; electronic limit switch is controlled by cam, Set position accurately and conveniently, and not affected by excessive handle.
Self-locking--Accurate worm and worm gear transfer large torque efficiently, high efficiency, low noise (Max. 50dB), long life,
with self-locking, prevent inversion, as stable and reliable transmission parts, no need to refuel.
Anti-off bolt--
The bolt attached to the shell and be not off when remove the shell.
Installation--
The installation size meets international standard ISO5211/DIN3337
Circuit--
Controlling circuit meets the single~phase or three~phase power supply standard, circuit layout is reasonable and
compact, terminals meet various of additional functional requirements effectively.
