Potable Water Valve Standards

Description This type of device is located in the domestic water distribution system and is designed to supply potable water to a drain trap to maintain the water seal. A means for the prevention of back-siphonage shall be incorporated as part of the device and shall...

Description Devices covered by this standard are self-contained, direct acting, single diaphragm types. Devices shall be permitted to have an integral strainer, separate strainer connected to the valve inlet, or be without strainer. Devices shall be permitted to be with or without an...

This standard describes 1-in. (25-mm) through 12-in. (300-mm) air valve and vent inflow preventer assemblies designed for use on the outlet of potable water distribution system air valves furnished in accordance with ANSI/AWWA C512 or storage facility vent pipes. The...

General This Standard covers potable water hygiene systems consisting of valves and fittings, electronic sensors, actuators, and control devices intended to ensure the hygienic transport of potable water and specifies requirements for materials, physical...

This European Standard applies primarily to copper alloy ball valves, dimensions DN 8 to DN 100, for potable water supply in buildings up to PN 10 and a distribution temperature of 65 C. Occasional excursions up to 90 C are permitted for a period of 1 h maximum. This standard...

This document specifies the field of application, the dimensional, the physico-chemical, the design, the hydraulic, the mechanical, and the acoustic characteristics of in-line anti vacuum valve family D Type A. This document covers in-line anti vacuum valve family D Type A, intended...

This standard describes the double check-valve backflow prevention assembly for potable water applications. The assembly shall be capable of withstanding a working water pressure of at least 150 psi (1,034 kPa) without damage to working parts or impairment of function...

The purpose of air valve and vent inflow preventer assemblies is to allow the release and admission of high volumes of air through air valves and air vents in potable water distribution systems, but prevent the entry of contaminated water when the air valve...

This document specifies: a) the field of application; b) the requirements for pressurised air inlet valves; c) the dimensional, the physico-chemical properties and the properties of general hydraulic, mechanical and acoustic design to which pressurised air inlet valves of nominal...

This specification covers triple-offset (see 6.3.4) torque seated (TOTS), quarter turn valves for fuel oil, aviation fuel, lubricating oil, seawater, auxiliary seawater, freshwater, chilled water, and potable water piping system services for shipboard use. The associated...

This Standard Practice covers in-line, internally spring-loaded (a), center-guided check valves made of gray iron or ductile iron. These valves, having the feature of limiting fluid flow to one direction only, are intended for use with clean fluids (i.e., fluids that do not contain...

This document specifies: a) the field of application; b) the requirements of hose union anti vacuum valves; c) dimensional and physio-chemical properties, and properties of general hydraulic, mechanical and acoustic design of hose union anti-vacuum valves of nominal sizes DN 15 up to...
