10Nm, 230V, 2 or 3-position control, running time 150s, IP 54

Emergency actuator Belimo series NFA-S2 for HVAC dampers or ball valves (e.g. Giacomini R250D with adapter). The actuator is designed for damper sizes up to approx. 2m2. The actuator control is open/close. The actuator includes two auxiliary switching contacts.

Function

In the event of a power interruption, the return spring begins to rotate the actuator to the default position. For example, in the event of a power failure, it closes the damper or ball valve. The same can be achieved in reverse, depending only on the initial position of the damper.

The actuator can be operated manually using a locking button and a manual crank.

Features

The actuator is protected against overload, no end stops are required.
Simple installation on the damper shaft using a universal bracket.
Adjustable working angle with mechanical stop.
The actuator can be equipped with auxiliary switching contacts S...A or a feedback potentiometer.
