AWWA C541-16(R21) Hydraulic and Pneumatic Cylinder and Vane-Type Actuators for Valves and Slide Gates, 2016
- Foreword [Go to Page]
- I. Introduction. [Go to Page]
- I.A. Background. This 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 [Go to Page]
- I.B. History. The 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
