Design, details of body ends, materials, marking and preparation for storage and transportation.

This British Standard specifies design, details of body ends, materials, test requirements, marking and preparation for storage and transportation, of copper alloy valves of globe, globe stop and check, check and gate types of the sizes specified in clause 5 and the pressure designation given in clause 6.

Two valve series, A and B, are specified (see clause 3), each series differing in its maximum temperature ratings.

The reclamation of valves through the impregnation of castings is a recognized practice within this standard but the impregnation process is not defined.

NOTE 1 The titles of the publications referred to in this standard are listed on the inside back cover.

NOTE 2 Valves which have failed the initial shell pressure test may be reclaimed, using an impregnation process which is permitted only by written approval of the purchaser and his acceptance of the manufacturer’s proposed method of reclamation.
