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

Properties

• The drive moves the ball valve into the operating position while tensioning the return spring. An interruption of the supply voltage turns the ball valve back to the emergency position thanks to the energy of the spring.
• Simple direct mounting on a ball valve with one screw. No additional adapter is needed for mounting. The mounting position can be selected in 90° steps in relation to the ball valve.
• The ball valve can be adjusted and fixed in any position with the hand lever. Unlocking is done manually or automatically by applying the supply voltage.
• The drive is secured against overload, does not need any end stops and remains automatically at the stop.
