STANDARD PRACTICE

SP-70.
This MSS Standard Practice was developed under the consensus of the MSS Technical Committee 106 and the MSS
Coordinating Com mittee. The content of this Standard Pra ctice is the resulting efforts of competent and expe rienced
volunteers to provide an effe ctive, clear, and non-exclusive standard that w ill benefit the industry as a w hole. This
MSS Standard Practice describes minimal requirements and is intended as a basis for common practice by the
manufacturer, the user, and the general public. The existence of an M SS Standard Practice does not in itself preclude
the manufacture, sale, or use of products not conforming to the Standard Practice. Mandatory conformance to this
Standard Practice is established only by reference in other documents such as a code, specification, sales contract, or
public law, as applicable. MSS has no power, nor does it undertake, to enforce or certify compliance with this
document. A ny certification or other statement of compliance with the requirem ents of this Standard Practice shall
not be attributable to MSS and is solely the responsibility of the certifier or maker of the statement.
Unless indicated otherwise within this MSS Standard Practice, other standards documents
referenced to herein are identified by the date of issue that was applicable to this Standard
Practice at the date of approval of this MSS Standard Practice (see Annex C). This Standard
Practice shall remain silent on the validity of those other standards of prior or subsequent dates of
issue even though applicable provisions may not have changed
By publication of this Standard Practice, no position is taken with respect to the validity of any potential claim(s) or
of any patent rights in connection therewith. MSS shall not be held responsible for identifying any patent rights.
Users are expressly advised that determination of patent rights and the risk of infringement of such rights are entirely
their responsibility.
In this Standard Practice, all text, notes, annexes, tables, figures, and references are construed to be e ssential to the
understanding of the message of the standard, and are considered normative unless indicated as supplemental . All
appendices, if included, that appear in this document are construed as supplemental . Note that supplemental
information does not include mandatory requirements.
U.S. customary units in this Standard Practice are the standard; (SI) metric units are for reference only.
Substantive changes in this 2011 edition are flagged by parallel bars as shown on
the margins of this paragraph. The spec ific detail of the change may be determined by
comparing the m aterial flagged with that in the previous edition.
Non-toleranced dimensions in this Standard Practice are nominal, and, unless otherwise specified, shall be
considered for reference only .

F O R E W O R D
The 1998 edition of MSS SP-70, in addition to various editorial changes, includes changes to: provide a
more complete metric version for reference use, delete the Class 800 Pressure-Temperature rating, and
expand Annex C to include ISO references.
The 2006 edition of MSS SP-70 included the following changes: 1) deleted ASTM A536 and ASTM A395
materials, since valves made of these materials will now be included in SP-128; 2) deleted PN designations since
these were easily confused with designations used in international standards that were based on other material
specifications and pressure-temperature rating procedures; 3) deleted DN designations in Table B1 resulting from
PN deletion; 4) ISO references were deleted from Annex C as a result of change 2 and 3 above; 5) added
minimum wall thickness requirements, that were previously omitted, in order to qualify the Class 125 and Class
250 ratings designations used in this Standard Practice; 6) added Type IV valves with illustrations; and 7)
replaced the terminology cast iron with gray iron.
This 2011 edition of MSS SP-70, in addition to various editorial and formatting updates, includes changes to:
(1) revise Section 4.1.4 by adding gray iron as an acceptable handwheel material; (2) clarify the leakage rate in
Section 7.4; and (3) update the organizations and references in Annex C.

5.11
ackseat
Valves shall be designed to
have a backseat. Repacking under pressure is
hazardous and is not recommended.
5.12
S t em s
5.12.1 The upper end of outside screw and
yoke valve stems and the lower end of non-
rising valve stems shall be threaded with
single or multiple Acme-type threads, or 60-
degree thread approximating the stub form,
formed to fit the engaging member.
5.12.2 Outside screw and yoke stems shall
be of sufficient length so as to be at least
flush with the top of the yoke nut after the
disc wedging has been worn into its lowest
position. The design shall be such as to
prevent the wedge or disc from leaving the
stem, or the stem from turning during the
operation of the valve.
5.12.3 Non-rising stem gate valves having
separate stem engaging members shall be so
designed as to prevent stem rotation or
pulling the stem out of the disc assembly or
wedge.
5.13 Handwheels Handwheels shall be of
the spoke type only. Webbed or disc type are
not permissible. Handwheels shall be marked
with the direction of movement for opening of
the valve.
5.14

otherwise specified by a purchaser, bypass and
drain connections shall be in accordance with
MSS SP-45.
6.
WORKMANSHIP
6.1
General
Valve parts shall be designed
and manufacturing tolerances set so as to
provide inter-changeability in the product of
any one manufacturer between units of the
same size, class, type, and design, except the
individual fit of the wedge or disc to the body
seats may vary.
6.2
Castings
All castings shall be clean and
sound without defects that may impair their
service. Plugging, impregnation, welding or
other repairing of defects is not permitted.
7.
T EST S
7.1General A shell test and a seat test shall
be made on all completed valves prior to
shipment by the manufacturer.
7.2 Shell Test
Valves in the partially open
position with both ends sealed shall be
subjected to hydrostatic or gas test pressure
specified in Table 2. No visible leakage is
permitted through the pressure boundary walls
or body-bonnet joint. Leakage through the
stem packing or stem seals shall not be cause
for rejection. The test pressure shall be held
for the duration specified in Table 3.
Caution: Safety precautions must be
taken when gas is used.

Valves shall be

than the maximum service pressure for which
the valve is rated. Test pressure shall be
applied successively on each side of the closed
gate, and the opposite side shall be checked
for leakage. As an alternate method for double
disc valves, the pressure may be applied inside
the bonnet or body with the discs closed and
both sides checked for leakage. The maximum
permissible leakage rate on each seat shall be
10 ml/hr/NPS. Test pressures shall be held for
periods specified in Table 3.
