EWNS Valve
March 2022
CAUTION
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.
The quantity of eyebolts for lifting purpose is the minimum recommendation. More eyebolts can be used per customer
experience. When tightening the eyebolts and nuts, do not exceed the torque that is specified on the diaphragm casing cap
screws and nuts (keys 119 and 120) in the following sections, to avoid damage on the diaphragm.
Lifting Valve/Actuator Assembly
To lift the EWNS valve assembly, ATI L264.5SRE80 actuator and accessories, the lifting ears located on the upper
cartridge should not be used 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
To lift the valve, eyebolts should be used. Insert 1-1/8-8 inch shouldered pattern eyebolts into four threaded holes
located on the top of the valve bonnet, positioned 90 degrees apart. The eyebolt material should be ASTM
A489-K04800 or stronger material. Be sure at least 90% of the threads are engaged in the receiving hole, with a
minimum thread engagement of at least 1-1/2 times the thread diameter in steel. If necessary, place lifting slings
around the inlet and outlet of the valve body for stabilization. Use padding as needed to protect any painted surfaces.
The valve can now be lifted using a hoist capable of leveling the lifting points.
Lifting Actuator Only
The ATI L264.5SRE80 actuator with accessories may be lifted using the lifting ears located on the upper cartridge. 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.

Installation

WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed
where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or
damage, provide a relief valve for over‐pressure protection as required by government or accepted industry codes and
good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
WARNING
Some bonnet flanges have a tapped hole that was used to handle the bonnet during manufacture. Do not use this tapped
hole to lift the valve assembly or personal injury may result.
