AKH3 PFA Lined Ball Valve

Fully PFA lined ball valve according ANSI

ATOMAC AKH3 PFA Lined Ball Valve

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 bar to 19 bar. Long-term protection against external leakage to the 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 protects against potentially dangerous electrostatic discharge and the anti-blow-out safety stem design eliminates the possibility of a blow-out. Also available as a V-port ball valve for precise modulating control services and various liner materials incl. conductive PFA.
