PRODUCT DESCRIPTION
Tecofi BSM6779 Stainless Steel NPT Ball Valve, Lever or Electric ON/OFF
BSM6779 is a Tecofi (France) full-bore stainless steel ball valve with NPT female threads, a CF8M body, 316 stainless steel ball and stem and an ISO 5211 top flange, in sizes 1/4″ to 4″. The datasheets cover two versions: -02 (lockable handle) and -J34 (with a 24–240 V 50/60 Hz electric actuator for ON/OFF operation). This page covers code BSM6779 only; its sibling BSM6179 (separate page) is identical in materials, ratings and dimensions but uses BSP threads to ISO 7/1 Rp.
Specifications
- Type: threaded ball valve, full bore, anti blow-out stem; ISO 5211 top flange
- Connection: NPT female thread, to ANSI B2.1
- Body and cap: stainless steel CF8M; ball and stem: stainless steel 316; ball seats: R-PTFE (15%); body gasket: PTFE
- Stem sealing: PTFE gland packing, Viton O-ring; double PTFE / FKM seal on the shaft
- Max. working pressure: 69 bar (1/4″–1″1/2) and 63 bar (2″–4″)
- Working temperature: -25°C to +180°C
- Medium: water, oil, compatible liquid products; design to EN 12516-1/-2 and EN 12266-1
- Version -02: lockable handle; version -J34: electric actuator 24–240 V 50/60 Hz, actuator recommendation for a maximum ΔP of 10 bar (16 bar: contact the manufacturer)
