Shutoff Valves for Trim and Drain Purposes for Fire Protection
Scope:
These requirements cover shutoff valves for trim and drain purposes for fire protection service. This standard covers valve constructions such as ball valves, butterfly valves, globe valves and plug valves. These valves are intended for installation and use in accordance with the following standards: Low Expansion Foam, NFPA 11; Sprinkler Systems, NFPA 13; Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, NFPA 13D; Sprinkler Systems in Low-Rise Residential Occupancies, NFPA 13R; Standpipe and Hose Systems, NFPA 14; Water Spray Fixed Systems for Fire Protection, NFPA 15; and Stationary Pumps for Fire Protection, NFPA 20.
Project need:
Proposed revisions to revise text throughout the standard to clarify requirements and update testing details. Proposed revisions to address requirements for features or accessories that can be incorporated as a part of valve assembly. These have consisted of sight glass features, an orifice to simulate the flow of water and sprinkler system pressure relief valves use to relieve excess pressure due to thermal expansion.
