2.3.2 Installed Face1oFace. The installed lace-to- lace dimension of certain buttertl valves (see Table II (Table 14), Note (6)1 may include allowances for gasket or resilient-facing compression. Refer to MSS SP-67 for definitive iLlustrations.
2.3.3 End4o-End. For those flanged valves where the gasket contact surfaces are not located at the extreme ends of the valve, the distance behseen the extreme ends is described as the end-to-end dimension and applies to flanged valves having the following nominal flange facing identifiers.
(a) ring joint
(b) large or small female
(c) laie or small groove
2.4 Buttweldlng End Valve Dimensions
For buttwelding end valves, the end-to-end dimension is the distance between the extreme ends (root faces) of the welding bevels (see Fig. 2).
Also see section 4.
2.5 Grooved End Valve Dimensions
The end-to-end dimension for grooved end valves is the distance between extreme ends.
2.6 Angle Valves
For flanged angle type valves (those in which the ends are at an angle of 90 deg to each other), the center-to- face dimension is the distance from the centerline of the port to the extwme end which is the gasket contact surface. For flanged angle type valves in which the gasket seating surface is not located at the extreme end and for angle type valves having huttwelding ends, the phrase center-to-end denotes the distance from the centerline of the port to the extreme end.
3 FACINGS OF FLANGED VALVES
Figure 1 shw facings for flanged ends.
3.1 Facings Normally Furnished
3.1.1 Flat Face. Flanges for Classes 25 and 125 cast Iron valves are flat faced.
3.1.2 2mm (0.06 in.) Raised Face. Flanges for Class
250 cast iron and for Classes 150 and 300 steel, alloy, and ductile iron valves have 2 mm (0i)6 in.) raised faces, which are included in the face-to-face (or center-to-face) dimension. When Classes ISO and 300 valves are required with flat faces, cither the full thickness of flangeor the thickness with the 2 mm (O.06 in.) raised faceremoved may be furnished, unless otherwvise specifiedby the customer.Users are reminded that removing the2 mm (O.06 in.) raised face will make the face-to-facedimension nonstandard.
3.1.3 7 mm (o.25 in.) Raised Face.Flanges forClass 600 and higher steel and alloy valves have 7 mm(0.25 in.) raised faces, which are included in the face-to-face (or center-to-face) dimensions.
3.2 Other Standard Facings
Table 9 (Table I-9)y summarizes data on all flange fac-ings and can be used with Tables 1 through 6 (Tables I-1through 1-6) in calculating face-to-face and end-to-enddimensions of flanged valves having standard facingsother than those described in para.3.1.
3.3 Ring Joint Facings
The X dimension given in Table 10 (Table I-10), whenadded to the face-to-face dimension of a valve havingraised face flanges in Tables 1 through 6 (Tables I-ithrough I-6), establishes the end-to-end dimension forthe valve having flanges with ring joint facings.
