Scope:

1.1  

This Standard applies to self-acting spring-operated devices that automatically reduce the initial pressure in water systems to a set lower pressure. It applies to devices that are of the direct-acting diaphragm type with a means for adjusting the pressure setting. Valves can be with or without an integral bypass relief valve or strainer.

1.2

This standard applies to nominal device sizes of ½, ¾, 1, 1 ¼, 1 ½, 2, 2 ½, 3, and 4 inches (DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, and DN100).

1.3  

This Standard provides requirements for material specifications, construction, structural integrity tests, capacity, reduced pressure deviations, instructions, and marking.

Project need:

To update the current standard due to user experience/feedback/new technology (new edition). This proposed New Edition is being developed at the request of the B64/B356 Technical Committee. It will provide the industry with up to date requirements for water pressure reducing valves used in potable water distribution systems.
