Belimo NVC24A-SR-TPC - linear actuator for globe valves

Belimo NVC24A-SR-TPC

Linear actuator designed for 2-way and 3-way globe valves. The Y control signal determines the actuator position, while voltage U is used for electrical position indication and can serve as a control signal for other actuators.

Key specifications

• Actuator force: 1000 N; stroke: 20 mm.
• Nominal voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Modulating control: operating range Y 2...10 V; position feedback signal U 2...10 V.
• Motor operating time: 35 s / 20 mm.
• Power consumption during operation: 3.5 W; in the rest position: 1.5 W; for cable sizing: 5.5 VA.
• Power and control connection: terminals with 1 m cable, 4x 0.75 mm² (4 mm² terminal).
• Degree of protection IEC/EN: IP54; protection class IEC/EN: III, Safety Extra-Low Voltage (SELV).

Operation and function

Manual adjustment is possible using a push-button that can be locked. The actuator allows the direction of movement to be changed and the setting range to be adapted: automatically when power is first switched on or by manual activation. It is protected against overload and stops automatically when the end stop is reached.
