3、 Approved by American National Standards Institute: May 21, 2002. ii AWWA Standard This document is an American Water Works Association (AWWA) standard. It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information no
4、rmally contained in specifications. The AWWA standards usually contain options that must be evaluated by the user of the standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA publication of a standard does not constitute endorsement of any
5、product or product type, nor does AWWA test, certify, or approve any product. The use of AWWA standards is entirely voluntary. AWWA standards are intended to represent a consensus of the water supply industry that the product described will provide satisfactory service. When AWWA revises or withdraw
6、s this standard, an official notice of action will be placed on the first page of the classified advertising section of Journal AWWA. The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official notice. American National Standard An Ameri
7、can National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an American National Standard does not in any respect preclud
8、e anyone, whether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Pr
9、oducers 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 American National Standards.

Requirements for power actuators are covered in ANSI/ AWWA C540, Standard for Power-Actuating Devices for Valves and Sluice Gates. 21.Time of operation for the power actuators (Sec. 4.3.2.8.5). 22.Special protective coatings, if other than specified as standard in Sec. 4.4.3. 23.Wh
20、ether or not records of certified tests are required (Sec. 5.1 and 5.2). 24.Sec. 5.1.2 requires the manufacturer to leak test the valve at the specified dif- ferential pressure of the valve. It is important to specify the operating differential pres- sure for the valve. Some ball valves rely on line
21、 pressure to seal and may have a higher leak rate at lower pressures if adjusted to seal at the rated pressure of the valve. Sec. 5.1.1.7 requires the manufacturer to test the valve for leakage at 100% of the specified differential pressure. The purchaser should specify any other required differenti
22、al pres- sures at which the valves are to be tested for leakage. 25.Affidavit of compliance, if required (Sec. 6.3). 26.Warranty provisions, if they are required. AWWA standards do not cover warranties. 27.If shop inspection is required, the extent of such inspection should be defined. Copyright 200

46、l apply in this standard: 1.Actuator:A device or mechanism used to restrain or move the ball. A power actuator requires fluid or electrical power to restrain or move the ball. 2.Ball:The rotating, internal structural member of the valve that forms a structural obstruction to flow through the pipelin
47、e when the valve is in the closed position. 3.Ball seat:Seating surface located on the ball. 4.Bearings:The bearings that support the ball and operating shaft. 5.Body seat:Seating surface located in the body. 6.Constructor:The party that furnishes the work and materials for placement or installation
48、. 7.Cosmetic defect:A blemish that has no effect on the ability of the component to meet the structural design and production test requirements of the standard. Should the blemish or the plugging, welding, grinding, or repairing of the blemish cause the component to fail these requirements, then the blemish shall be considered a structural defect. 8.Design or rated pressure:The maximum internal, steady-state pressure, at the specified operating temperatures, which the valve is designed to withstand when the ball is in any position. 9.Differential pressure:The maximum steady-
