Belimo SY8-230A-3-T – actuator for butterfly valves

Rotary actuator designed for butterfly valves in stationary heating, ventilation and air conditioning systems. The technical data sheet indicates that it is particularly suitable for outdoor applications.

Key features and specifications

• Motor torque: 1500 Nm; rotation angle: 90°.
• Rated voltage: AC 230 V; operating range: AC 207...253 V; frequency: 50/60 Hz.
• Control: Close/Open, 3-point; motor operating time: 60 s / 90°.
• Power consumption during operation: 722 W; rated power: 759 VA.
• Auxiliary switches: 2x SPDT, 1x 3° / 1x 87°.
• Power / control connection: 2.5 mm² terminals (2x 1,5 mm² or 1x 2,5 mm² cable).
• Flange connection: F14; enclosure protection rating: IP67.
• Mechanical, integrated position indicator and temporary manual override using a handwheel.
• Internal heater to prevent condensation.
• Ambient temperature: -30...65°C [-22...149°F].

The actuator can be mounted directly on the butterfly valve. Internal limit switches cut off power to the motor, and the mechanical rotation angle stops are factory-set to -2° and 92° and must not be changed. Installation work must be carried out by suitably qualified personnel.
