DR24A-SR-7 Rotary Actuator, 90 Nm, AC/DC 24 V, 150 s - Belimo | ideal for butterfly valves

DR24A-SR-7 Rotary Actuator, 90 Nm, AC/DC 24 V, 150 s

• IP54
• Max. torque 90 Nm
• AC/DC 24 V, modulating
• Running time 150 s / 90°
• Operating range DC 2...10 V
• Position feedback DC 2…10 V
• Manual override temporary, permanent
• Connection cable length 1 m (PVC)

Mode of operation: The actuator is connected with a standard modulating signal of DC 0...10V and drives to the position defined by the positioning signal. Measuring voltage U serves for the electrical display of the valve position 0...100% and as slave control signal for other actuators.

Simple direct mounting: Simple direct mounting on the butterfly valve. The mounting orientation in relation to the butterfly valve can be selected in 90° (angle) increments.

Manual override: Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).

High functional reliability: The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.

Combination valve/actuator: For valves with the following mechanical specifications in accordance with ISO 5211 F07: - Square stem head SW = 17 mm for form-fit coupling of the rotary actuator. - Hole circle d = 70 mm

Torque not constant: Due to the non linear torque characteristic the actuator can only be used for butterfly valves and not for other armatures.
