Multi-turn Electric Actuators

suit a wide range of multi-turn applications. They provide a reliable position control of gate, stop valves, as well as similar

Characteristic
	903 series actuators have a wide torque range from 50Nm to 6000Nm and the five base sizes can matching different valves.
	The versatility of 903 series actuators. There are standard actuator, actuator with control package, folomatic control unit could be selected according to demand.
	903 series actuators can have explosion-proof enclosure to ExdIIBT4(GB3836.1,GB3836.2).
	903 series actuators (include ex-proof units) with IP65(GB4208-84) enclosure can ensure complete protection from dust and moisture. IP67,IP68 enclosure can be provided if need.
	For the 9030~9032 units, the shift from manual to motor operation is semiautomatic. For the 9033~9035 units, easy changeover is possible.
