Type LP linear pneumatic actuators regulate dampers, inlet vanes, louvers, lever operated valves, turbine governors, fluid drives and other final control elements. The input signals provide modulating control to position the final control element in a linear motion or rotary motion via lever linkage.
“Simple Cylinder” Type LP Linear pneumatic actuators are supplied with either type AV conventional or type TZIDC digital positioners mounted on the cylinder. Cylinders are supplied with a threaded clevis on the rod end. Base mounting pivots can be ordered as an accessory. A protective boot is optional.
Type UP Pneumatic Universal Rotary Actuators regulate dampers, fan inlet vanes, lever-operated valves, turbine governors, fluid drives and other final control elements.
The control signals provide modulating or on/off control power to position devices through mechanical linkage or by direct coupling. Types UP1 and UP2 actuators include a double-acting rotary vane power unit. Types UP3, UP4, UP5, UP6 and UP7 actuators include a double-acting cylinder with a motion conversion mechanism to convert linear to rotary motion.
All ABB actuators offer continuous control with a virtually wear-free operation, as well as the highest positioning accuracy and stability available, regardless of positioning time.
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.
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.
