The UP7 is a universal pneumatic rotary actuator designed for modulating or on/off control of final control elements such as dampers and valves. It delivers a rated torque of 7326 N⋅m (5400 lbf⋅ft) at a maximum supply pressure of 552 kPa (80 psig). The actuator uses a double-acting piston with a motion conversion mechanism to generate 90° rotary output. It supports control inputs of 4 to 20 mA with EDP300 or TZIDC digital positioners, offering fail-safe or fail-in-place operation, and includes HART communication capability. The actuator has an IP24 (NEMA 3R) standard enclosure, with IP66 (NEMA 4X) optional. Physical dimensions include a cylinder size of 30.5 x 41 cm (12 x 16 in), and it is compatible with optional accessories such as alarm/travel switches, air failure lock, strip heaters, and volume boosters. Weight with positioner is 379 kg (836 lb).
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.
