Three-piece medium-pressure ball valve intended for demanding applications and for fittings precision ( instrumentation ) for industry chemical, petrochemical, pharmaceutical, power generation, process engineering – for liquids and for gases. intended for mounting in-line. valve is characterized high range size for ensuring appropriate large flow, tightness closing (permissible leakage internal through sealing the ball 0.1 Ncm 3 /min), high durable and low torque swivel. each valve is tested pressure nitrogen. Certified according to ISO 15848-1:2006 (E). lever valve with a lock standard in color yellow, available Levers o shape oval. Body material: AISI 316 steel (ASTM A351 CF8M, cast). Material Connections: steel AISI 316 (ASTM A351 CF3M, cast). Material the ball and stem: steel AISI 316. Material lever: steel AISI 304, PVC. sealing the ball: PTFE (standard); available versions with other material seals o higher parameters (modified PTFE, PTFE with powder steel stainless, UHMWPE, PEEK). sealing stem: MG1241 (PTFE with fiber glass and graphite) / PTFE (standard). pressure working (dependent od temperatures / material seal – see chart): up to 103 bar (PTFE). temperature use (dependent od material seal – see chart): up to +186°C (PTFE). Connection: inch LET-LOK®. notes! The ball valves are designed to work in a completely open or completely closed position. valves have factory adjusted sealing gland for pressure 70 bar. Due to varied conditions use, can be required periodic regulation seal using screws seal stem (po removal lever). recommended is initial regulation against starting installation.
