Description Devices covered by this standard are designed primarily to supply water to drain traps which have infrequent use and in which water evaporation would allow sewer gas to enter the premises. This device is located in the domestic water distribution system and is...

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...

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 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...

This document specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It does not apply to chemical service glass-enamel and apparatus enamel.

This International Standard specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It is not applicable for chemical service glass-enamel and apparatus enamel.

This standard defines the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It is not valid for chemical service glass-enamel and apparatus enamel.

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 International Standard specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It is not applicable for chemical service glass-enamel and apparatus enamel.

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 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...

ASSE 1081 provides performance standards and testing procedures for pressure reducing boiler feed valves that offer protection of the potable water supply by means of an integral backflow preventer with an intermediate atmospheric vent. Devices covered by this standard are...

This document specifies: - the field of application; - the requirements for in-line anti-vacuum valves; - the dimensional, the physico-chemical properties and the properties of general hydraulic, mechanical and acoustic design to which in-line anti-vacuum valves of nominal sizes DN 8...

FOREWORD On the 1st January 2015 the SAE Industry Technologies Consortia (SAE ITC) acquired the ADS Aerospace Standards, previously known as the Society of British Aerospace Companies (SBAC) Aerospace Standards. The SAE ITC established in 2003 operates as a trade association as part of the SAE...

The safe and efficient operation of a liquid piping system is dependent on the continual removal of air and wastewater gases from the liquid piping system. Choosing the proper air valve for the application is critical to all liquid piping systems. This manual provides essential information...

This part of ISO 13693 specifies the construction and performance requirement and test methods for metal-bodied chemigation valves with water at temperatures not exceeding 50 °C, which might contain fertilizers and chemicals of the types and concentration used in agriculture. The...

This Standard applies to in line-valves for use in radiant heating systems, and hot and cold water cross linked polyethylene (PEX) distribution systems which are compliant with the requirements identified in ASTM F877 for PEX tubing systems. Valves meeting these requirements...
