| 7<\/td>\n | Foreword I.\tIntroduction. I.A.\tBackground.\u2003This standard describes hydraulic and pneumatic cylinder- and vane-type actuating devices that are externally mounted on gate, ball, plug, cone, globe, knife gate, and butterfly valves and on slide gates suitable for use in water and wast I.B.\tHistory.\u2003The first edition of the ANSI\/AWWA C540 standard, published in 1987, was the result of 12 years of effort by the AWWA Standards Committee on Power-Actuating Devices for Valves and Sluice Gates. The committee was formed by AWWA in 1974 and ch II.\tSpecial Issues. II.A.\tDiscussion.\u2003ANSI\/AWWA C541 describes only the design and performance of those actuating devices applied to systems with operating pressures normally encountered in water and wastewater utilities.
