2.4.4
When mounting a 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
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.
