Short description

Output drive type A consisting of output mounting flange [1] with axial bearing stem

nut [2].The stem nut transmits the torque from the actuator hollow shaft to the valve

stem [3]. Output drive type A can withstand thrusts.

To adapt the actuators to available output drive types A with flanges F10 and F14

(year of manufacture 2009 and earlier), an adapter is required.The adapter can be

ordered from AUMA.
