Installation
Key numbers in this procedure are shown in figures 11, 12, and 13 unless otherwise indicated.
WARNING
Always wear protective gloves, clothing and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the bursting of pressure retaining parts, be certain the service
conditions do not exceed either the valve body rating or the flange joint rating, or other limits given in table 4 or on the
nameplate. Use pressure‐relieving or pressure‐limiting devices to prevent the service conditions from exceeding these
limits.
If installing into an existing application, also refer to the warning at the beginning of the Maintenance section on page 9 in
this manual.
