Source: ABB Measurement & Analytics
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 and UP6 actuators include a double-acting piston with a motion conversion mechanism to convert linear to rotary motion.
