The purpose of a water pressure reducing valve for domestic water distribution systems is to reduce static and flowing pressures in water distribution systems. 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 integral by-pass relief valve.
