The Argus EK71 ball valve with its many innovative design features represents the highest standards in valve technology and is designed to meet the API-6D, ANSI 16.34 and BS 5351 requirements. One piece low temperature forged Carbon Steel body design (end entry) with superfine finished seat supported ball, anti-blowout 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.

Features & Benefits
- Improved plant and personnel safety from valve design, which meets fugitive emission standard ISO 15848
- Scalloped Seat design to prevent solids and particulate from building in the seat pocket
- Special bearing configurations, including cladding of critical areas and trim coating configurations, improve valve life-time
- Designed for temperatures 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
