Air Relief Valves allow trapped air to be released from piping systems without losing system pressure. They prevent pipeline damage due to pressure surges caused by trapped air.
Air release valves permit trapped air to be released from piping systems without losing water pressure. The small orifice releases air under pressure during normal pipeline operation. The float is connected to the vent via a linkage mechanism which is capable of operating the vent under full pipeline pressure. Rated at 300 psi. UL Listed, FM Approved. Fusion Bonded Epoxy Coated Interior and Exterior to AWWA C550 Standard.
Dual air release vents the accumulated small volumes of air during normal system operation. Allows venting of large volumes of air during pipeline filling. Provides protection from pipeline collapse due to vacuum. Flanged to ANSI B16.1, Class 125. Other flange types available upon request. Fusion Bonded Epoxy Coated Interior and Exterior to AWWA C550. UL Listed.
Provides the functions of both Air Release Valve and Air / Vacuum Valves. Exhausts large quantities of air at start-up. Provides protection from pipeline collapse due to vacuum. Incorporates both features into one valve. More compact and economical.
