RHDE250 Electrical ​Rotary Actuator (Contrac)

Brand: ABB Group

Compact actuator for the operation of final control elements with rotary movement. 

For continuous positioning, in explosion-proof design, rated torque 250 Nm (185 lbf-ft). 

The actuator thrust rod transfers the force directly to the final control element.
