HOW TO ORDER A.I.L. CAST STEEL VALVES
A.I.L. Valves are identified by a four digit figure number derived as follows:
As a standard, A.I.L. Valves are in Carbon Steel to ASTM A216 Gr. WCB. For Valves in special shell material which can also be offered, suffix the following abbreviations to the four digit figure number.
ASTM A217 Gr. WC6 : WC6
ASTM A217 Gr. WC9 : WC9
ASTM A352 Gr. LCB/LCC : LCB/LCC
Gear Operation : GO
Electrical Actuator : E
