Rotary actuator with fail-safe function NRFA-O for two and three-way ball valves Belimo. Suitable for both open/close versions and regulating versions of ball valves.

Actuator version NO - open without voltage.

Features

Without electrical voltage, the actuator keeps the valve open. When power is supplied, the actuator moves the valve to the working position, while the return spring is tensioned. When the power is interrupted, the spring reopens the valve.
Simple direct mounting on the ball valve using a single screw. No additional adapter is needed for installation. The mounting position is selectable in 90° increments relative to the ball valve.
The ball valve can be adjusted and fixed in any position using the manual lever. Unlocking is done manually or automatically by supplying power.
The actuator is protected against overload, requires no end stops, and automatically stops at the limit.
