Lifting Valve/Actuator Assembly; Lifting Valve Only; Lifting Actuator Only - Emerson Fisher NS2 Yoke Instruction Manual

ATI Piston Actuator
June 2023
NOTICE
Care must be taken when lifting the valve/actuator assembly to ensure all accessories and tubing are not damaged in the
process. Accessories and tubing may need to be removed prior to lifting to prevent damage and properly reinstalled before
use. Protect valve flange faces, butt weld ends, and other connection surfaces from damage during lifting.

Lifting Valve/Actuator Assembly

To lift the valve assembly, ATI actuator and accessories, the assembly should not be lifted by the actuator alone. It is
also necessary to place lifting slings around the inlet and outlet of the valve body for lifting. Use padding as needed to
protect any painted surfaces. The valve/actuator assembly can be lifted using a hoist capable of leveling the lifting
points.

Lifting Valve Only

For guidance on lifting only the valve, please refer to the instruction manual for the applicable valve.

Lifting Actuator Only

The ATI L264.5SRE80 actuator with accessories may be lifted using the lifting ears located on the upper cartridge. The
load rating for these lifting ears is 28.7 kN (6,400 lbf) and should not be exceeded. A single hoist lift point on the strap
or chain will balance and lift the actuator, keeping it level. Use padding as needed to protect any painted surfaces.
The ATI L224.5SRR80 actuator with accessories may be lifted using appropriately rated hoist rings threaded into the
two 3/4-10 UNC threaded holes provided in the upper head, see figure 2. The load rating for these threaded holes is
10,000 lbf (44.8 kN) combined and should not be exceeded. A single hoist lift point on the strap or chain will balance
and lift the actuator, keeping it level. Use padding as needed to protect any painted surfaces.
