The FLOWSERVE ATOMAC AtoStar stainless steel, PFA lined ball valves deliver improved performance, reliability and safety. AtoStar full port valves provide bubble tight shutoff, low maintenance, no-leak stem seals and the safety assurance of a blowout-proof stem assembly. AtoStar ball valves meet ASME, DIN and JIS standards. AtoStars are very suitable for use in the pharmaceutical and semiconductor industries. AtoStars are also available as a V-port valve for precise modulating control services, or can be fitted with a C-ball for internal cavity cleaning purposes. The AtoStar spare parts are interchangeable with the balance of the lined Atomac ball valve range. The AtoStar ball valve range consists of six models:
AS1 with Face-to-Face dimensions per DIN EN 558-1 (as our AKH2), AKH2.2 – DIN version) flanged per DIN PN16
AS2 with Face-to-Face dimensions per ANSI (as our AKH2 and AKH2.2 – ANSI version), flanged per ANSI B 16.5 class 150
AS3 with Face-to-Face dimensions per ANSI B 16.10 (as our AKH3 and AKH2A), flanged per ANSI B 16.5 class 150
AS4 with Face-to-Face dimensions per ANSI B 16.10 – short pattern (as our AKH3 and AKH2A), flanged per JIS 10 K
AS5 with Face-to-Face dimensions per Japanese Industrial Standard, flanged per JIS 10 K
AS6 AtoStar with integral heating jacket for critical applications
