STANDARD PRACTICE

SS

•

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.

DESIGN

5.0General When under the test pressure

specified in Section 7, valves shall be

the valve is operated at full rated working

pressure.

5.1 Minimum

W all R equirem ents

Valves'

bodies and bonnets shall meet the minimum

wall thickness requirements specified in

ASM E B 16.1 for the same NPS and Class

gray iron fitting.

End flanges shall be

integral with the valve body. Dimensions,

tolerances and drilling shall be in accordance

with ASME B 16.1 for each NPS and

respective pressure class and shall have a

5.7.2 Double discs shall be provided with

guides and linkage or disc spreading devices

between the gates or a combination of these

which will hold the gates in proper relation

with each other and the stem, and will

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.

otherwise specified by a purchaser, bypass and

drain connections shall be in accordance with

MSS SP-45.

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.

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.
