quarter-turn electric actuators

详情

seal:through the process surface phosphor and plastic spraying, the aluminum 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.

form arrangement:mechanical components and electronic module can be easy to dismantle, thus improving the conditions of the assembly and maintenance repair and the conditions of replacing the electronic components.

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.

motor:BN series motor is high torque and low inertia motor so that the motor can start with rated load and stop instantly. when actuator is blocked, the temperature of the motor will rise up quickly, once up to **0℃,the switch installed in the motor will cut off the circuit so as to protect the motor and control systems. when the motor temperature drops to a certain temperature, the switch will connect circuits. motor insulation class is F.

servo controller:the whole package circuit has the feature of anti-seismic and goodmoistureproof. electronic brake system can fix position without oscillation effect.damping characteristics is zero cycle.
