2.4.4 Mounting the Actuator in a Vertical Orientation on a Horizontal Stem
When mounting an Bettis EHO Actuator in a vertical orientation, the Spring Module
must be positioned up. The actuator may be supported by using two straps in the
configuration shown in Figure 6. A third strap or small chain may be attached to the
stabilization tab on spring module to balance the unit while lifting. The weight of the
actuator must be supported by the straps running over the spring module and under the
drive module flange.
Figure 6 Vertical Actuator Lift
CAUTION:
Never lift the actuator with a valve attached. Always handle actuator/valve assemblies
by attaching lifting equipment to the valve only.
NOTE:
When a vertical EHO Actuator is mounted to the valve, and in its final orientation, the
spring module must be up and outboard end of the power cylinder positioned below
the Hydraulic Reservoir Breather. If not possible, contact Bettis for further instructions
on piping to elevate the breather.
