The UP3 pneumatic rotary actuator converts linear piston motion to 90° rotary output for damper and valve control, delivering up to 1085 N·m (800 lbf·ft) torque at 690 kPa (100 psig) supply pressure. It has a carbon steel frame and output shaft, die-cast aluminum housing with nitrile seals, and an IP24 (NEMA 3R) standard enclosure with IP66 (NEMA 4X) optional. Control inputs include 4-20 mA with AV, EDP300, or TZIDC positioners, or 120 V AC/125 V DC solenoids for on/off operation. It supports fail-safe or fail-in-place modes, air failure lock, and optional heated enclosures or shaft position transmitters. Operating temperature range is up to 85 °C (185 °F) with digital positioners. The actuator is 778.8 mm long, with 1/2-14 NPT air supply connection and 1/4-18 NPT signal port. Shipping weight is 145 kg (320 lb) with positioner.
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.
