Rotary actuator with fail-safe function NRF for two and three-way Belimo ball valves. It can be used both for open/closed versions and for control versions of ball valves. The actuator is controlled by a DC 0-10V control signal.

NC actuator version - normally closed.

The actuator is only compatible with Belimo ball valves. The actuator cannot be used for valves of other manufacturers!

Features

• The actuator carries the ball valve while tensioning the return spring to the operating position. Power supply interruption turns the ball valve back to the fail-safe position due to the spring energy.
• Simple direct mounting on ball valve with one screw. No additional adapter required. The mounting position in relation to the ball valve is selectable in 90° increments.
• The ball valve can be adjusted and fixed in any position using the hand lever. Unlocking is done manually or automatically by applying power.
• The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached
