Small Single Orifice Air Valve with Ball Isolation Valve Product Information

Small single orifice air valve with ball isolation valve is one important exhaust valve in the long big piping transport, which is normally mounted on the top of the pipe or pipe air holding place to discharge the air in the pipe, making sure the pipe work normally. Slow closing type combined vent valve can remove the air existed in the pipe more flexible, proventing of the pressure fluctuation or other damages in the piping system. It is applicable especially to the main water pipes and deep well pumps piping system. Flowspec Luokai can manufacture and supply the small single orifice air valve with ball isolation valve according to standard of BS EN1074-4:2000, BS5163:2004 with sizes of 1/2”~ 1-1/4” (DN15 ~ DN32mm). Welcome to contact us for detailed information and best quotes if you have any questions or inquiries.
