WARNING
Under no circumstances should N7 gagecocks be
used for steam-water applications unless they are
equipped with one of the optional features. Use
of standard N7 gagecocks without these features
can result in sudden release of pressure causing
serious personal injury or property damage.
2.2 Design ratings at maximum and minimum
operating temperatures
To determine the maximum allowable working
pressure for a specific temperature within the
design limits stated in Table 1, the user must
refer to applicable technical data sheets, or
when provided, the specifically stated design
limits on a product proposal.
2.3 Application data
Note:
For specific application data, within the
above ranges, consult the product proposal for
the specific model and size gagecock set, or
request the supply of the applicable technical
data sheet.
WARNING
Never exceed these design ratings or application
data limits. Exceeding design ratings or
application data limits can cause serious personal
injury or property damage.
3 INSPECTION & PERFORMANCE
CONFIRMATION
3.1 Receiving inspection
Upon receipt of a gagecock set, check all
components carefully for damage incurred in
shipping. If damage is evident or suspected,
do not attempt installation. Notify the carrier
immediately and request a damage inspection.
3.2 User’s rating inspection
The user is to confirm:
1. That the gagecock set model number and
pressure/temperature rating stamped on
nameplate (163) conform to the description
on the user’s purchase order.
2. That the operating conditions described in
the purchase order agree with the actual
operating conditions at the installation site.
3. That the actual operating conditions at the
installation site are within the application
data shown on the applicable technical data
sheet or product proposal referred to above.
4. That the materials of construction of the
gagecocks are compatible with both the
contained fluid and surrounding atmosphere
in the specific application.
Important:
If the size, model or performance
data of the gagecock set as received does not
conform with any of the criteria above, do not
proceed with installation. Contact an authorized
Penberthy distributor for direction.
