Functions and Equipment
The actuators support open-close and modulating duties. SAI actuators are rated for short-time duty (S2 - 10 min), while SARI actuators are for intermittent duty (S4 - 25%). Features include limit and torque switches, mechanical position indicators, and compatibility with AUMA valve gearboxes and linear thrust units.
