For this product we offer the service of actuator assembly with armature. More information

Belimo SFA actuator with fail-safe for ball valves (eg. Giacomini R250D with adapter ). The actuator is designed for damper size up to approx. 4m2. The actuator is controlled by a 0-10V signal. Communication takes place via the Belimo MP-BUS. The actuator is suitable for the Loxone system.

Functions

In the event of a power failure, the return spring begins to rotate the actuator to the starting position. Eg. closes the damper or ball valve in the event of a power failure. The same can be done upside down, depending only on the initial position of the valve.

• By using the hand crank the valve can be operated manually and egaged with the locking switch at any position.
• Optional control parameters: Open/closed, 3-point, DC 0,5 - 30V.

Features

• The actuator is overload protected, no end stops are required.
• Simple mounting on the ball valve with only one screw.
• Adjustable working angle with mechanical stop.
• The actuator can be retrofitted with auxiliary changeover contacts S ... A or with a feedback potentiometer.
