SCOPE AND FIELD OF APPLICATION This Standard Practice covers carbon steel, iron or ductile iron, cast or fabricated, bonnetless, unlined knife gate valves with flanged or lugged ends from size NPS 2 (DN 50) through NPS 60 (DN 1500). The valves identified in this Standard...
This Standard specifies requirements for PN 16 and PN 35 solid gate metal-bodied metalseated gate valves for waterworks purposes, with a maximum operating temperature of 40°C. This Standard is applicable to the following versions: (a) Valves of nominal sizes DN 80 to DN...
This standard covers flanged cast-iron gate valves in sizes NPS 2 through 24 correspnoding th nominal pipe sozes in ANSI B36.10. This standard covers valves in pressure Claases 125 and 250 in ANSI B16.1 The valve is the outside screw-and-yoke (OS&Y) type with rising...
This standard covers ductile iron gate valves with flanged ends, in sizes NPS 1 ½ through 24, corresponding to nominal pipe sizes in ANSI B36.10. This standard covers valves in Classes 150 and 300, as specified in ANSI B16.42. The vales covered are the outside screw-and-yoke...
This Standard specifies requirements for PN 16 and PN 25 metal-bodied resilient-seated gate valves for waterworks purposes, with a maximum operating temperature of 40°C. This Standard is applicable to the following versions: (a) Valves of nominal sizes DN 80 to DN 750 with...
Requirements for flanged and threaded end valves for general purposes in sizes DN 10 to DN 1000 for flange valves and ½ to 6 for threaded end valves for nominal pressures in the range PN 6 to PN 25.
This standard specifies requirements for the design, functional characteristics and manufacture of gate valves made of thermoplastics materials intended for isolating service, their connection to the pipe system, the body materials and their pressure/temperature
This standard covers steel venture gate valves with flanged and buttwedling ends, in sizes NPS 2 through 24, corresponding to nominal pipe sizes in ANSI B36.10. The term veturi describes a valve with seat openings appreciably smaller than the end ports. This standard covers...
