The UP1 is a universal pneumatic rotary actuator with a double-acting rotary vane power unit, providing up to 122 N·m (90 lbf·ft) torque at 690 kPa (100 psig) supply pressure. It delivers a 90° rotary stroke, adjustable from 80° to 92°, with 655 cm³ (40 in³) volume displacement. Control input options include 21-103 kPa (3-15 psig) or 21-186 kPa (3-27 psig) pneumatic signals, or 4-20 mA electrical signal with fail-safe or fail-in-place modes. The actuator features a standard IP24 (NEMA 3R) enclosure, with IP66 (NEMA 4X) optional. Air supply connection is 1/4-18 NPT female. Ambient temperature range is up to 85 °C (185 °F). Manual operation is via a lever-type mechanism with locking bolt. Shipping weight is 25 kg (55 lb) with positioner, 23 kg (50 lb) with solenoid. Mounting bolt circle is 127 mm (5 in), shaft diameter is 12.7 mm (0.5 in).
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.
