Rotary actuator with SRFA emergency function for two and three-way Belimo ball valves. It can be used both for open / closed versions and for control versions of ball valves.

NC drive 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 emergency 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
