Specification for Steel globe and globe stop and check valves (flanged and butt-welding ends) for the petroleum, petrochemical and allied industries

Specification for
Steel globe and globe stop and check valves
(flanged and butt-welding ends) for
the petroleum, petrochemical and
allied industries
BS 1873

This British Standard specifies requirements for cast or forged carbon and alloy steel outside screw
and yoke globe and globe stop and check valves, straight pattern, angle pattern and (oblique) Y
pattern, with flanged or butt-welding ends in nominal sizes within the range of 15 mm to 400 mm
(; in to 16 in) and Classes 150 to 2500. This standard can also be used as a general guide where
valves of material composition outside the scope of section three of this standard are required as, for
example, for use in highly corrosive services or environments or for low temperatures

The standard can be adapted to apply to valves with needle type seats in 15 mm (; in) an 20 mm (< in) nominal sizes which will meet all requirements of this standard, except that the valve seat bore is
reduced and the needle point may be either integral with or loose on the stem.
