An MSS Standard Practice Is Intended as a basis tor common practice by the manufacturer, the user, and the general public. The existence of an MSS Standard Practice does not in Itself preclude the manufacture, sale, or use of products not conforming to the Standard Practice, Mandatory con formance is established only by reference In a code, specification, sales contract, or public law, as applicable.
Where some slight shift of the absolute value of the minimum and maximum dimensions permitted by the Inch dimensions and those provided by the converted metric dimensions do not unacceptably affect the functional or safety characteristics oHhe fitting, the metric conversions have been rounded to whole millimetre values in order to facilitate ease of measurement by ordinary measuring tapes or rulers with non-magnllled vision. Furthermore, the rounding has not always been made to the nearest whole millimetre. In some cases It has been made to the whole millimetre which would facilitate tables manifesting logical Increments in both the dimensions and their tolerances. It Is recognized that the introduction of such variances will create a conflict In the acceptance dimensions or gaging between the inch end metric data. Experience Indicates a probability that no serious difficulties will result from this conflict Hence, it is the intent of this standard that any dimension which Is within tolerance by either metric or inch measurement Is considered to be in conformance with this standard.
Substantive changes in this 1979edition are '`flagged" by parallel bars as shown on the margins of this paragraph. The specific detail of the change may be determined by comparing the material flagged with that Jn the previous edition.

2. PRESSURE-TEMPERATURE RATINGS
2,J The pressure-temperature ratings in Table 1 apply to all products covered by this Standard Practice. Valves conforming to the requirements of' this Standard Practice must, in all respects, merit these ratings.
2.2 These ratings are the maximum allow able non-shock pressures at (he temperatures shown, and allowable pressures may be inter polated between temperatures shown,
2.3 Rating Temperature; The temperature shown corresponding to the pressure rating shall be the material temperature of the pressure retaining structure. In view of the various environments in which piping com ponents may be installed (fe. - insulated or not, and either heated or cooled), it Is as sumed that the material temperature of the pressure retaining structure is the temperature of the contained fluid. Use of a pressure rating at a material temperature other than the temperature of the contained fluid is the responsibility of the user, and subject to the requirements of applicable codes. '
2.4 The safe pressure-temperature rating of a solder-joint pipe system is dependent, not oniy on valve, fitting and tubing strength but also on the composition of the solder used
for joints. Pressure-temperature ratings for solder joints made with typical commercial solders are given In Annex A. It shall be the responsibility of the user to select a solder composition that is compatible with the service conditions; (as well as to assure ade quacy of workmanship employed in making the joints).
2.5 The ratings given In Table 1 at -20F to 150F (-30 to 65C) shall also apply at lower temperatures. Products that are to operate at low temperatures shall conform to the rules of the applicable codes under which they are to be used,
2.6 The safe pressure-temperature rating of valves fitted with non-metallic disc, (Le., globe and angle valves, Type 2 and check valves. Types 2 and 4), is dependent upon the composition of the disc material. It shall be the responsibility of the user to specify the service application. When no service appli cation is specified, discs suitable for steam service at rated working conditions shall be furnished in all bronze globe and angle valves, Type 2 and in all bronze check valves, Types 2 and 4, Users are advised to consult with the manufacturer in cases of doubt.

3. MATERIALS
3.1 General - All valve components manu factured to this standard shall be made from materials produced under recognized quality control procedures. Recommended materials are listed in Table 2.
3.2 Castings - All castings shall be clean and sound, without defects which will impair their service. No plugging, welding, repairing or impregnating of any defects is allowed. ,
3.3 Users are cautioned against application with fluids which may react chemically with any material used in these valves. Consul tation with the manufacturer is advised to determine suitability in cases of doubt.
3.4 In certain areas of the country, where water conditions are particularly "aggressive", piping components made from certain zinc bearing copper-base alloys are susceptible to a form of corrosion known as dezincificatlon. Consultation with local water works division Or manufacturers is advised to determine suitability in cases of doubt.
DESIGN
4.1 General - Valves shall be of substantial construction to resist permanent distortion under normal service conditions and shall be free of imperfections and defects which may be injurious to the performance of the valve.
4.2 Flow Passage Area
I 4.2.1 The flow passageway of bronze gate I valves, shall have a minimum area of not less
than the area of a circle having a diameter equal to the nominal pipe size except that valves fitted with seat rings may reduce the passageway area by the area of the seat ring driving lugs. The valve shall bo so designed that the stem and/or wedge clear the water way when the valve is fully open.
4.2.2 The flow passageway of bronze globe and angle valves, Types 1 and 2, designed with integral seats and when fully open, shall have an area at all points equal to the area of a circle having a diameter equal to the nom inal pipe size except the area through the seat may be reduced by the area of the disc guides.
4.2.3 The flow passageway area of bronze
globe and angle valves, Type 3, of the fUll
flow design, may be reduced by the area of
the seat ring driving lugs.
4.2.4 The flow passageway of bronze globe and angle valves, Type 3, of the plug design, for throttling service, may have a reduced area through the seat.
4.2.5 The flow passageway of bronze check valves. Types 3 and 4, shall have a minimum area of not less than the area of a circle having a diameter equal to the nominal pipe size except that valves fitted with seat rings may reduce the passageway area by the area of the seat ring driving lugs.

The length of paoking in contact with the stem shall be at least one diameter of the stem passing through it. The thread of the packing nut shall be of sufficient length to enable the nut to be screwed on to the stuffing box at least two full tlireads when the full amount of packing 1$ in place and the length of thread engagement between the stuffing box and the packing nut shall be sufficient for full travel of the gland follower.
4,6,2 Stem Packing; Stem packing shall be lubricated or graphited asbestos or tetrafluoroethylene impregnated asbestos of the braided, twisted, or formed ring type suitable for the pressure-temperature rating of the valve.
4.7 Handwheels for Bronze Gate Valves, and Bronze Globe and Angle Valves

5.1 All valves shall be legibly marked in
accordance with the requirements of MSS
SP-25.
5.2 All bronze check valve bodies shall be
legibly marked to indicate the direction of flow by means of an arrow cast on the valve body or. the word "In" or "inlet" cast or stamped on the inlet end of the body.
6. TOLERANCE
Tolerance specified in the standards refer* enced for dimensions shall be applied to these valves.
7. INSPECTION AND TESTING
7.1 All valve parts shall be made within inspection limits which will insure ready interchangeability of parts.

I. This annex contains the metric version of the following Pressure-Temperature Rating, Table C-l.
II. Pressure-Temperature Rating, Table 1: The table in this annex was developed by using the equation of the P-T curve between 65- deg. C and 208 deg. C Or 288 deg, C and calculating the pressure in bars (gage) for the temperatures listed in Table C 1 of this annex. The conversion unit for 1 bar is equal to 14.5038 pounds per square Inch,
HI. Conversion of Dimensions to Metric Equivalents:
A. The dimensions listed below, which are usually listed as two place decimals In the standards, shall be considered to be fractions when converting the dimension -
( Handwheel diameter.
B. All other decimals shall be considered to be exact decimal dimensions for the purposes of this conversion. Examples: stem diameters, length of pipe threads, deptii of thread chamber, etc.
C. Significant Figures: The following rules shall be applied for rounding the metric equivalents calculated in accordance with A and B above.
1. Fractions round to nearest mm (25).
2. Decimals - round to one decimal place (25.0).
