2.2. Valve Categories
The valve categories are as follows:
Gate valve
Globe valve
Check valve
Alloy valves
Small steel and ferritic alloy steel valves
Brass valves

2.3. Non-Standard Valves
Certain type valves do not conform entirely to ASME pressure and
temperature ratings or the standards mentioned
in
this specification.
In
such
cases, valves that differ somewhat
in
pressure rating or temperature limits
from those of the manufacturer and model number listed in the material
requisitions may be offered. Any exceptions to the description in the material
requisition form, however, must
be
clearly noted
in
the quotation.
2.4. Material Substitutions
Alternative valve designs suitable for the service in the requisition forms may
be offered separately. Valve bodies of 9 chrome may be offered when the

executed by the manufacturer only
in
the following cases:
Valves with ASME rating 900 pound and higher.
Valves bodies and bonnets made by weld assembly of segments of
castings, forgings, bars, tubular products or plates or combinations. All
pressure retaining welds shall be examined in accordance with ASME
SEC.vIlI-division I for 100 of the valves to assure a weld joint
efficiency of 1.0. Certified records of these tests shall

3.5. Nu mber
of
Valves
to
be Tested
Valves to be tested in the presence of ENPPI inspector are as follows:
For nominal valves sizes 24 inch and smaller and rating up to 300
pound ASME, the number of valves to
be
tested = Square root of the
quantity in the lot.
For nominal valves sizes 14 inch and smaller and rating
Up
to 800
pound ASME, the number of valves
to be
tested square root of the
quantity in the lot
For nominal valves sizes 16 inch and larger
and
rating
up
to 800 pound
ASME, all valves shall be tested.
For nominal valves all sizes rating greater than 900 pound ASME, all
valves shall
be
tested.
For nominal valve sizes larger than 26 inches, all valves shall
be
tested.
3.6. Repa ir s
Repair of shell defects in cast steel valves, as defined in the applicable
ASTM, code are permitted only after the consent of approval by ENPPI
on
the manufacturer s repair weld procedure.
Casting repairs of cast iron and ductile iron valves is not permitted.
Repair of castings mechanical means with metal plugs, or
impregnation with metallic or non metallic materials are not permitted.
