Flanged Ball Valves AKH3

The FLOWSERVE ATOMAC AKH3 is an ANSI B16.10 short pattern, 150 lbs., standard port, lined ball valve with a minimum cavity space. The floating ball design ensures bubble-tight shut-off across the pressure range of 1 mbar to 19 bar. Long term protection against external leakage to atmosphere is provided by PTFE chevron packing rings in a deep stuffing box, the substantial body flanges and the moulded liner seal.

An anti static device provides protection against potentially dangerous electrostatic discharge and the anti blow-out safety stem design eliminates the possibility of a blow-out. Also available as V-port ball valve for precise modulating control services and various liner materials incl. conductive PFA.
