PURGEnVENT Manual and Automatic Air Venting Valves - Brochure

NFPA 13 (2016) standard requires the addition of an air vent on each wet fire sprinkler system to help mitigate internal pipe corrosion. PURGEnVENT™ Air Venting Valves are designed to work alone or in tandem to eliminate as much excess air from the wet fire sprinkler system as possible.
