1. SCOPE(’)

I.

1 This MS S Stand ard Practice covers flanged

end, flangeless end, threaded end, socket welding

end, and butt-welding end compact steel

globe

and check valves. The term “Compact” is used

to identify the valves covered by this Standard

Practice a s reduced seat port(2) valves. Valve

sizes correspond to nominal pipe sizes listed in

AS M E/ AN SI B36.10M and B36.19M. Flanged,

flangeless, and butt weld end valves are limited

to sizes NP S 4 and smaller; threaded and socket-

welding end valves are limited to sizes NPS 2

and smaller. Valves covered under this Stan dard

Practice shall meet the requirements of ASME

B16.34, “Standard Class”. The following valves

are covered by this Standard Practice:

d) Piston, ball, spring controlled piston,

inline, or ball and swing check valves, in all

classes, bonnet designs and end connections

NOTES:

a)

Temperature limitations on bolting are as follows:

Gr B7, 1000F; Gr L7, 1000F; Gr B16, 1100F; Gr

B8-CI 1,1500F; Gr B8M-CL 1,1500F; G rB8-CL 2,

1000F and Gr B 8M-CL 2,1000F.

bl Upon prolonged exposures to temperatures above

800F, the carbide phase of carbon steel may be

converted to graphite.

Only killed steel shall be used above 850F.

(d )ASTMA 320, Gr L7 bolts, and AST M A 194, Gr

4

nuts are also acceptable.

e ) AS TM A 193, G r B8-CL

and G r B8M-CL 1 bolting

may be substituted, provided that the requirements

of 3.4 are met.

O AST M A 193, Gr B8-CL 2 bolts are

also

acceptable.

(g) Use normalized and tempered material only.

(h)A STM A 194, Gr 7 nuts are also acceptable.

6) At temperatures over 1000F, use only when the

carbon is 0.04 percent or higher.
