Ball valve 3-piece with connection inch LET-LOK®, steel stainless, H-500

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 in-line mounting. The valve is characterized by a large size range to ensure an adequately 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 pressure-tested with nitrogen. Certified according to ISO 15848-1:2006 (E). lever valve with a lock standard in color yellow, Available Levers o shape oval. Material the body: steel AISI 316 (ASTM A351 CF8M, cast). Material the connection: 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 temperature / material seal - see chart): up to 103 bar (PTFE). Operating temperature (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. The valves have a factory-adjusted gland seal for a pressure of 70 bar. Due to varied working conditions, periodic adjustment of the seal by means of the stem seal screw may be required (after removing the lever). recommended is initial adjustment against starting installation.
