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

Actuator version NO - open without power.

The actuator is exclusively compatible with Belimo ball valves. It cannot be used on valves from other manufacturers!

Features

The actuator drives the ball valve while simultaneously tensioning the return spring to the operating position. Interrupting the power supply turns the ball valve back to the fail-safe position using the spring's energy.
Simple direct mounting on the ball valve with a single screw. No additional adapter is required 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 applying power.
The actuator is protected against overload, requires no end stops, and automatically stops at the stop.
