FOREWORD

This

Foreword is not part

of

ASME 816.33-1990.)

Th e B16 Standards Co mm ittee was organized in the Spring of 1920 and held its or-

ganizational meeting on November 21 of that year. The group op erate d as a Sectional

Com mittee, later redesignated as a Standards Comm ittee), under th e authorization of

the Am erican Engineering Standards Committee, subsequently named A merican Stan-

dards Association, United States of America Standa rds Institute and now, Am erican

National Stan dards Institute). Sponsors for the group were T he Am erican Society of

Mechanical Engineers, Manufacturers Standardization Society

of

the Valve Fittings

Industry, and the Heating and Piping Contractors National Association, later the Me-

chanical Contractors Association of America.)

Th e American Gas Association determ ined that standardization of gas shut-off valves

used in distribution services was desirable and needed . Th e A.G.A. Task Comm ittee on

Standards for Valves and Shut-Offs was formed and development work commenced in

1958. In 1968, it was determined that a more acceptable document would result if ap-

proval were gained from the American National Standa rds Institute ando facilitate such

action, the A.G.A. Committee became Subcommittee No. 13

of

the B16 activity.

The standard offers more performance requirements than has been customary in the

B16 standards. It is expected that this will permit both m anufacturers an d users greater

latitude in producing and using products made to this standard.

Work was agonizingly slow as the group gradually developed the docum ent in the

desired form at. I ts efforts were successful when, on July 18, 1973, final approval was

granted by the Institute.

This revision incorporated some major revisions to the format. In addition, the scope

of the standard was clarified so that the standard could be applicable to all manually

operated metallic gas valves for use in gas piping standa rds up to 125 psig. T he revised

standard incorporated testing criteria for valves which could have a specific pressure

rating within this p ressure range. This revision was made to clarify the fact tha t the

standard is also applicable to valves with service design ations other than 60 psig and 125

psig. Th e revision was approved o n F ebruary 10 1981.

The 1990 revision has d eleted th e sampling inspection table on the basis that the scope

clearly limits this standard t o turning torqu e values at the time of manufacture. Th is

edition establishes

U.S.

customary units as the standard and metric equivalents are de-

leted.

In 1982, American National Standards Committee B16 was recognized as an ASME

Com mittee operating under procedures accredited by ANS I.

Following approval by th e B16 Comm ittee and AS ME , this revision to the1981 Edition

of this Standard was approved as an American National Standard by ANSI on August

24 1990.

All requests for interpretations or suggestions for revisions should be sent to th e Sec-

retary, B16 Committee, The American Society of Mechanical Engineers, United Engi-

neering Center, 345 East 47th S treet, New York, N.Y. 10017.

in conformance with

a

prior edition of reference

standards and n all other respects conforming to this

standard will be considered to be in conformance

even though the edition reference may be changed

in a subsequent revision of this standard.

2 CONSTRUCTION

2.1 General

Each valve at the time of manufacture shall be

capable of m eeting the requirem ents set forth in this

standard. The workmanship employed

in

the manu-

facture

and assembly of each valve shall provide gas

tightness, safety, and reliability of performance and

freedom from injurious imperfections and defects.

the action of the gases such as

natural, manufactured and

LP

gases.

2.3 Tamp er-Proo f Features

Where valves are specified

to

be tamper-proof,

they shall be designed and constructed to minimize

the po ssibility of the removal

of

the core of the valve

with o ther than specialized tools.

2.4 Conf igura t ion

2.4.1 Operat in g Indicat ion.

Th e valve shall be so

marked or constructed that the operator can visually

determine:

u)

when a

2.5 Marking

2.5.1 General.

Except as may be m odified herein,

valves shall be marked

as

required in MSS SP-25 and

shall include th e following requirements.

2.5.1.1 Name.

The manufacturers’ name or

trademark and where space permits the designation

“B16.33” is desirable.

2.5.1.2 Pressure Rating.

Marking for pressure

rating shall be in acco rdance with 4.4 of

MSS SP 25.

These designations, such as 60G, 125G , etc., may be

shown on the head o r stem.

2.5.1.3 Tamper-Proof.

The designation

“T”

for

tamper-proof construction where tamper-proof fea-

turesare not easily identifiable without disassem-

bling the valve. This designation may be shown on

the head or stem.

2.6 Lubrication (Sealant)

Valves which require pressure lubrication by the

injection of lubricant through fittings to the sealing

surfaces of the valve) shall be capable of being lu-

bricated while subjected to the p ressure rating. Com-

pliance with this provision can be met if lubrication

can be accomplished with the’valve in both the fully

opened and the fullyclosed position. Th e design

must be such as

to

minimize entry of lubricant into

the gasway when lubricated in accordance with the

manufacturer’s instruction.

3DESIGNQUALIFICATION

3.1 General

3.1.1

Each b asicvalve design shall be qualified and

demonstrated as suitable for the service by testing

randomly selected production valves of each size,

type and pressure shell material according to thede-

sign qualification tests.

3.1.2

All tests, unless otherw ise specified herein,

shall be conducted at a tempe rature of 74°F 15°F.

3.1.3

Before each test is condu cted, thevalve shall

be in th e condition in which it would be placed in

service.

3.2

Gas Tightness

The valve shall provide a shut-off when in the

closed position and shall not leak to the atmosphere

in the opene d or losed position when subjected pro-

gressively to internal air pressure of first 4 2 psig

and then to at least 1.5 times the pressure rating of

the valve.

3.2.1 Method of Test For Gas Tightn ess.

With

the valve n theopened position and heoutlet

plugged, the test pressure hall be applied to th e nlet

of the valve. The valve shall

be

immersed in a bath

containing water at a tem pera ture of 74°F

5°F

for

a period of 15 seconds. Leakage, as evidenced by the

flow breaking away) of bubbles shall not be permit-

ted. The valve shall then be urned to the closed

position, outlet opened and the test repeated.

3.2.1.1

Other means of leak detection may be

used provided they can be shown to be equivalent in

leak detection sensitivity.

3.3 Temp eratu re Resistance

A

valve shall be operable at temperatures ranging

from -20°F to 150°F without affecting the capability

of the valve to control the flow of gas.

Th e valve shall be m aintained at a tem pera ture of

-20°F for a period long enough to allow all pa rts to

come to equilibrium temperature. With the valve

subjected to an internalair pressure a t least equal to

the pressure rating and with outlet end

of

valve ar-

ranged to vent to atmosphere it shall be determined

that it can be opened and closed.

The valve shall then be maintained at a tempera-

ture of 150°F for a period long enough to allow all

parts to come to equilibrium temperatures. With the

valve subjected to an internal air pressure at least

equal to the pressure rating it shall be determ ined

that it can be op ened and closed.

Th e valve shall then be allowed to return to a tem-

perature of 74°F r+ 15’F and satisfactorily pass the

test outlined in 3.2.

3.4.1 Strengt h. A

valve in the open position with

the outlet plugged, shall withstand an internal hy-

drostatic pressure of425 psig for a period of on e

minute without rupture or perma nent deformation

that would, after release of the pressure, render the

valve inoperable.

3.4.2 Twis t.

The valve body, when tested in both

the opene d and closed position, shall withstand th e

torque specified in Table 1 applied directly to the

ends of the valve, without rupture or permanentde-

formation that would, after release of the torque,

render the valve inoperable, incapable of providing

a shut-off, or cause it to leak to atmosphere when

tested as outlined in 3.2.

3.4.3

Bending.

A

valve, in both the opene d and

closed position, shall withstand th e ben ding mom ent

specified in Table

2

when applied as indicated in

Figure 1 without rupture. After the bending stress

is relieved, there shall be no p erman ent deform ation

that w ould render the valve inoperable, incapable of

providing a shut-off, or cause it to leak to atmos phere

when tested as outlined in 3.2.

3.4.4 Tensile Strength.

A valve,n both the

open ed and closed position, shall withstand the ten-

sile load specified in Tab le 3, when app lied gradually

to valve ends, without rupture or permanent defor-

mation that would, after release of the tensile load,

render the valve inoperable, incapable of providing

a shut-off, or cause it to leak to atmo sphere when

tested as outlined in 3.2. Schedule 80 steel pipe shall

be connected to the valve for the purpose of trans-

mitting the tensile load.

3.4.5 Turning Torque.

The torque equired to

continue to op era te the valve after breaking loose

from its set or stationary position shall not exceed
