On special application, Pacific valves can be supplied with special end flange facings other than the raised face or ring joint. The most popular special flange facings are shown below include large male-female, large tongue-groove, small male-female small tongue-groove. STANDARDS Special flange facings supplied on Pacific valves conform to ANSI B. B.. templates flange thickness "Q" for ring joint end flanges are identical to the corresponding size class raised face flanges shown on preceding page. Special Facings FINISH (large male female) Stard finish of gasket surface is serrated, either spiral or concentric, with -0RA finish. FINISH (small male female tongue groove) Stard finish of gasket surface is -0 micro-inch maximum roughness. FACE-TO-FACE Face-to-face dimensions of Pacific valves with special flange facing will be in accordance with B.0 will be furnished upon application.

Depth of groove or female is 0.9 in. on all sizes classes. Raised portion or full face may be furnished unless otherwise specified on order. For small male female joints care should be taken in the use of these dimensions to insure that the inside diameter of fitting or pipe is small enough to permit sufficient bearing surface to prevent the crushing of the gasket. This applies particularly on lines where the joint is made on the end of the pipe. Inside diameter of fitting should match inside diameter of pipe as specified by purchaser. male female faces large tongue groove are not applicable to Class 0 because of potential dimensional conflicts.
