Actuator Mounting
Mounting actuator is easiest with valve shaft pointing
vertically upwards, but mounting is possible in any
other position.
Actuator should be mounted to ensure sufficient
room to easily remove housing cover and access
internal components for wiring and repair.
Actuators are supplied with female drive output.
Output drive bushing is removable for ease of
machining or replacing.
Standard ISO 5211 bolt patterns are provided on
mounting base. Actuator must be firmly secured to a
sturdy mounting bracket or directly to the valve’s ISO
mounting pad. High tensile bolts or studs with spring
locking washers must be used. To avoid backlash,
there should be no flexibility in the mounting.
Valve output shaft must be in line with actuator
output drive to avoid side-loading the shaft. Operate
with handwheel before fully tightening mounting
hardware to ensure correct alignment.
Ensure both valve and actuator are in the same
open or closed position before mounting.
CAUTION:
Prior to mounting, the actuator must be
checked for any damage. Damaged parts must
be replaced by original spare parts only.
