Belimo SRFA-S2-O – actuator for ball valves

Rotary actuator with fail-safe function: during operation, it tensions the return spring; when the power supply fails, the spring moves the valve to the safety position. The position when power is off is NO, valve open (A–AB = 100%). For valves with an L-type port, the manufacturer specifies A–AB = 0%.
