Datasheet Summary
Powered by GS/AI

The RHD1250 is an electrical rotary actuator designed for continuous positioning, three-point control, or bus control of valve flaps and ball valves, with a rated torque of 1250 Nm (920 lbf-ft), adjustable to 50%, 75%, or 100% of nominal torque. It operates in S9-100% stall-proof mode per IEC 60034-1, with an IP66 and NEMA 4X rating, and is suitable for ambient temperatures from -10 to 65 °C. The actuator features adjustable mechanical limit stops, a handwheel for manual operation, and a maintenance-free design rated for up to 10 years under normal load. Power and signals are supplied exclusively through a separate electronic unit, with options for 115 V AC or 230 V AC. The output shaft has a keyway, and the unit is equipped with a 24-pole plug connection. It supports analog (4-20 mA), HART®, or PROFIBUS DP® communication and includes a spring-loaded brake for fail-safe freeze action.
