502 series electric actuators

502 Series Electric Actuators

502 series electric actuators suit a wide range of quarter-turn applications. They provide a reliable position control of butterfly, ball valves, as well as similar ones.

The patent integrative design. The reduction mechanism is placed in the watertight house even the output torque reaches 5000Nm. So the compact profiles provide the 502 series higher reliability and watertightness.
The versatility of 502 series actuators. There are standard actuator, actuator with control package, folomatic control unit could be selected according to demand.
The 502 series actuators can have explosion-proof enclosure to ExdIIBT4(GB3836.1,GB3836.2).
The 502 series actuators (include ex-proof units)with IP65 (GB4208) enclosure can ensure complete protection from dust and moisture. IP67,IP68 enclosure can be provided if need.

The shift from manual to motor operation is fully automatic and no hand/auto lever is provided. The handwheel could be operated in motor mode, which only affect the output speed slightly.
