Belimo SRF24A-SR-O rotary actuator

The actuator for ball valves operates with a Y control signal. When moving the valve to its operating position, it tensions the return spring. If the power supply is interrupted, the spring moves the valve to the NO safety position — valve open (A – AB = 100%). For valves with an L-port, the documentation specifies A – AB = 0%.
