| 7<\/td>\n | Foreword I.\tIntroduction. I.A.\tBackground.\u2003This standard covers electric motor actuators that are externally mounted on gate, ball, plug, cone, globe, and butterfly valves, and on slide gates suitable for use in water, wastewater, and reclaimed water utilities. This standard does 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.\u2003At the time this standard was approved, numerous AWWA standards define valves or slide gates that may be operated by electric actuators. The standards listed here refer to this standard for electric actuators and do not include separate <\/td>\n<\/tr>\n | ||||||
