ISA Training course catalogue released
The ISA Training Institute has released its latest course catalogue, detailing more than 300 instructor-led, CD-ROM, online, web-based, and video courses, from August 2003 to March 2004
This standard applies to integral flanged globe-style control valves, sizes 15 mm (1/2 inch) through 400 mm (16 inches), having top, top and bottom, port, or cage guiding.
The standard will aid users in their piping design by providing Class 125 flat face, and Classes 150, 250, 300, and 600 raised face, flanged control valve dimensions, without giving special consideration of the equipment manufacturer to be used.
The second standard in the group is ISA-75.08.05 (reaffirmation of ANSI/ISA-75.08.05-2002), "Face-to-Face Dimensions for Buttweld-End Globe-Style Control Valves (Classes 150, 300, 600, 900, 1500, and 2500)".
This standard applies to buttweld-end globe-style control valves, sizes 15 mm through 450 mm for Classes 150 through 2500.
The standard helps in piping designs by providing buttweld-end globestyle control valve dimensions, regardless of manufacturer.
A third standard was also submitted for approval.
ISA-75.08.06 (reaffirmation of ANSI/ISA-75.08.06-2002), "Face-to-Face Dimensions for Flanged Globe-Style Control Valve Bodies (Classes 900, 1500, and 2500)".
Focuses on flanged globe-style control valves, sizes 15 mm (1/2 inch) through 450 mm (18 inches), having top, top and bottom, port, or cage guiding.
The standard will help users in their piping design by providing Classes 900, 1500, and 2500, flanged globe-style control valve dimensions, without giving special consideration to the equipment manufacturer to be used.
