Any special considerations, supply drawings if necessary.
The standard Batescrew flange, listed on the following page, is a
modified ‘Table D’ flange (AS 2129).
It has the table D Pitch Circle Diameter and number of holes, but
flange thickness and bolt diameter are reduced to sizes appropriate for
the specified operating heads. Valves fitted with these flanges may
therefore be connected to a standard table D flange, using the smaller
bolts listed in the table.
Flanges complying with other recognised standards, eg. AS 2129 table A; DIN 2530 CL6; ANSI 125; JIS5; may be supplied, at extra cost. These would normally be used only when it is necessary to comply with specific regulations.
