The Argus FK79 ball valve with its many innovative design features represents the highest standard in valvetechnology and is designed to meet the API 6D, ANSI 16.34 and BS 5351 requirements. Split body design with superfine finished seat supported ball, anti-blow-out stem, compact ball seats and anti-static device. Long life double stem seal system and stem supported in bearings to ensure seals are free from operating loads. Stem sealing construction complies with the latest TA-Luft and EPA (method 21) fugitive emissions requirements and fire-safe to BS 6755 and API 607.

Features & Benefits
- Improved plant and personnel safety from valve design, which meets fugitive emission standard ISO 15848
- Scalloped Seat design to prevent solids and particualte from builidng in the seat pocket
- Special bearing configurations, including cladding of critical areas and trim coating configurations, improve valve life-time
- Designed for temperatures up to +1022°F for the highest demands on valve tightness in process and to atmosphere (FE)
- Chambered ball seats, seat pocket body design, stem seal protection and flushing system designs support valve performance and extend service life-time
- Process optimized coatings, cladding option and wearing protection feature for extended ball valve life-time
- Flushing options in critical valve areas (e.g., on seats, stem or cavity) avoid media build up to improve service-life time
- High performance designs for high pressure, metal to metal seat gas tightness solutions in oxygen service
