Water Pressure Reducing Valves for Domestic Water Supply Systems
|Publication Date:||1 August 1979|
This Standard covers material specifications, construction requirements, and tests for structural integrity, capacity and reduced pressure deviations, and instructions and marking.
Application and Scope
This Standard applies to devices that automatically reduce the initial supply pressure to a set lower pressure in domestic water systems. It applies to devices in the size range 1/2 - 2 inches inclusive that are of the direct acting diaphragm type with a means for adjusting the pressure setting, and are suitable for use over a hydrostatic inlet pressure range up to 1700 kPa and a water temperature range up to 82°C.
