Electrical actuators
Electrical actuators are designed for longest maintenance-free operation.They feature an oil-lubricated spur gear with drive shafts supported by ball bearings. Rotary motion is converted to linear motion in the linear actuator by means of a highly efficient ball screw spindle. Contrac actuators are characterized by a deadband of just ± 0.05%, providing high-accuracy positioning for all valve types. With their robust design and IP66/NEMA 4X protection, Contrac actuators withstand even the most arduous operating conditions.

Our offering

Rotary actuators

Electrical rotary actuators with rated torque of 100 Nm ... 16000 Nm for the operation of final control elements with preferably 90° rotary movement such as flaps, cocks, dampers, etc.A lever / linkage bar assembly transfers the torque or the actuator is directly coupled to the cock flange. 

Electrical rotary actuators of the RHDE… series are designed for the use in hazardous areas. They are controlled via standard electronic units, loaded with specific data for the explosion-proof actuators. These electronic units for field or rack installation are installed in the non-hazardous area.

Linear actuators

Electrical linear actuators of the LME... / RSD ... series are the optimal solution for the operation of final control elements with preferably linear movement. The internal rotary / linear conversion is done virtually wear-free and the actuator thrust rod transfers the force directly to the final control element.

Electrical linear actuators of the RSDE… series are designed for the use in hazardous areas. They are controlled via standard electronic units, loaded with specific data for the explosion-proof actuators. These electronic units for field or rack installation are installed in the non-hazardous area.

  • Rated force of 20 kN (4500lbf)

         -RSD20 - V68642

         -RSDE20 - V68645

  • Rated force of 50 kN (11240lbf)

         -RSD50 - V68652

         -RSDE50 - V68655

  • Rated force of 100 kN (22500lbf)

         -RSD100 - V68662

 

 

 


Electronic units

Electronic units for field installation and mounting rack installation control the actuators. They are fed with 115 or 230 V AC. A local control panel allows for easy basic settings.
If they are used for the control of actuators in explosion-proof design, they require actuator specific data and they are installed outside the hazardous area.
