Belimo SR24A-SR - rotary actuator for ball valves

Belimo SR24A-SR rotary actuator

Modulating actuator for ball valves. The control signal Y determines the actuator position, while the feedback voltage U enables electrical readout of the valve position.

Key features

• Rated voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Y operating range: 2...10 V; position feedback signal U: 2...10 V.
• Running time: 90 s / 90°; positioning accuracy: ±5%.
• Power consumption during operation: 2.5 W; at rest: 0.4 W; wire sizing power: 5 VA.
• Power and control connection: 1 m cable, 4x 0.75 mm².
• Manual adjustment by push-button with lock option; mechanical position indicator and adjustable mechanical rotation angle stops.
