Belimo NRQ24A-SZ - rotary actuator for ball valves

Belimo NRQ24A-SZ – actuator for ball valves

Rotary actuator with modulating control. Signal Y determines the actuator position, while voltage U is used for electrical indication of the valve position.

Key features and specifications

• Motor torque: 8 Nm.
• Rated voltage: AC/DC 24 V; rated voltage frequency: 50/60 Hz.
• Operating range of signal Y: 0.5...10 V; position feedback U: 0.5...10 V.
• Motor running time: 9 s / 90°.
• Power consumption during operation: 13 W; at rest: 2 W; wire sizing power: 23 VA.
• Power and control connection: 1 m cable, 4x 0.75 mm².
• Manual adjustment by push-button with locking option; adjustable angle of rotation with mechanical stops.
• Manual adaptation, automatic on initial power-up.
• IEC/EN degree of protection: IP54; ambient temperature: -30...40°C.

Direct mounting on the ball valve is performed using one central screw. Parallel operation of actuators is permitted, taking their specification data into account.
