American Na- tional Standards are subject to periodic review, and
9、users are cautioned to obtain the latest editions. Producers of goods made in conformity with an American National Standard are encouraged to state on their own responsibility in advertising and promotional materials or on tags or labels that the goods are produced in conformity with particular Amer

Ca u t i o n n o t i C e : The American National Standards Institute (ANSI) approval date on the front cover of this standard indicates comple- tion of the ANSI approval process. This American National Standard may be revised or withdrawn at any time. ANSI procedures require

26、Background. I.A. This standard describes hydraulic and pneumatic cylinder- and vane-type-actuating devices that are externally mounted on gate, ball, plug, cone, globe, and butterfly valves and on slide gates suitable for use in water utilities. This standard does not cover pilot and control apparat
27、us used to actuate the operating device. History. I.B. 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 charge
28、d with the development of standards on prime movers for valves and sluice gates, including electric motors and cylinders employing air, water, and oil. The second edition of the ANSI/AWWA C540 standard was approved by the AWWA Board of Directors on June 6, 1993, and added quarter-turn actuators. The
29、 third edition was approved on June 16, 2002. It added vane-type actuators and digital controls. In 2004, the original single standard was split by the Standards Council into two separate standards, one for electric motor-actuated devices (C542) and this one (C541) for hydraulic and pneumatic cylind
30、er and vane-type actuators. These two standards replace the ANSI/AWWA C540 standard. This first edition of ANSI/ AWWA C541 was approved on January 27, 2008. Acceptance. I.C. NSF/ANSI 60 Drinking Water ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects are not ap
31、plicable to this standard. Special Issues. II. Discussion. II.A. At the time this standard was approved, existing AWWA standards reference ANSI/AWWA C540 rather than include the new separate power- actuator standards, ANSI/AWWA C542, Electric Motor Actuated Devices for Valves and Slide Gates, and AN
32、SI/AWWA C541, Hydraulic and Pneumatic Cylinders and Vane-Type Actuators for Valves and Slide Gates. ANSI/AWWA C541 describes only the design and performance of those actuating devices applied to systems with operating pressures normally encountered in water utilities. Purchasers of hydraulic and pne
33、umatic cylinder- and vane-type-actuating devices should carefully review the requirements of this standard, evaluate the ForewordThis foreword is for information only and is not a part of ANSI/AWWA C541.

34、ided to the manufacturer, and review the data to be supplied by the manufacturer. Such evaluations are essential to ensure proper application of hydraulic and pneumatic cylinder and vane-type actuated device for the intended use. Specific requirements for controls and accessories and other items not
35、 described in this standard must be included in the purchase documents. Hydraulic Fluid. II.B. Caution should be used in the selection of a hydraulic fluid to be used in a cylinder actuator. In the event of a malfunction involving leakage of fluid into the water supply, it is essential that the hydr
36、aulic fluid not impart any taste or odor or contain any organic or inorganic substance harmful to the water supply or the consuming public. If potable water is used as the hydraulic fluid, care must be taken to prevent backflow of this water back into the potable system. Use of This Standard. III. I
37、t is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered. This standard includes certain options that must be selected and specified by the purchaser to completely describe an
38、d obtain the actuator desired. In addition to the factors in Sec. III.A, Purchaser Options and Alternatives, other factors to be considered when sizing an actuator are described in Sec. 4.3, Actuator Sizing. The following summarizes the options that must be selected and the data that should be cover
39、ed in the purchase documents covering actuators manufactured in accordance with this standard: Purchaser Options and Alternatives. III.A. The following items should be provided or requested by the purchaser: Standard usedthat is, ANSI/AWWA C541, Hydraulic and Pneumatic 1. Cylinder and Vane-Type Actu
