DESCRIPTION
This standard BS : Specification for steel globe and globe stop and check valves (flanged and butt-welding ends) for the petroleum, petrochemical and allied industries is classified in these ICS categories:
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 (½ in to 16 in) and Classes 150 to . 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 (see clause 37).
The standard can be adapted to apply to valves with needle type seats in 15 mm (½ in) an 20 mm (¾ 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.
Straight, angle and (oblique) Y pattern with flanged or butt-welding ends in nominal sizes from 15 to 400 mm (½ to 16 in) and Class 150 to .
BS Standard Cast Steel BB Manual Globe Valve Class 150 ASME B16.5
BS Standard High Pressure Cast Steel BB Manual Globe Valve Class 150
Designed to BS / API 600 and pressure tested in accordance with API 598/EN-1. This heavy duty flanged globe valve offers durability throughout a wide range of industrial applications, boiler plant and rugged environments. Handwheel operated and offered in both ANSI 150, offering maximum service life.
The seat Ring and Wedge Disc are ground and lapped to a mirror finish that provides matching sealing surfaces. A plug type disc is supplied as standard with flat and regulating type discs available on request. Heat treated stainless steel STEM with precision machined ACME threads for long lasting service. Machined Backseat Bushing to provide a secondary metal-metal stem seal. Rising Stem gives open and closed indication of position with large diameter Handwheel for easy operation. Austenitic ductile iron YOKE SLEEVE gives resistance to heat, corrosion and wear. Two piece self-aligning GLAND BUSHING and GLAND FLANGE to prevent damage with high strength alloy steel STUD BOLTS.
