Saudi Valves Manufacturing 06 Flanged Butterfly Valves Saudi Valves Manufacturing Product features Materials (basic equipment) Design and type acc. Body, disk and bearing covers of ductile cast iron to EN 593 / API 609 / AWWA C-504 EN-GJS-400-15 (GGG-40) or EN-GJS-500-7 (GGG-50) Flange connection acc. Shafts of stainless steel X20Cr13 (1.4021) to DIN EN 1092-2 / ANSI B16.5 Seat in the body of CrNi steel Face to face dimension acc. to DIN EN 558-1, Shaft bearings of bronze series 14 (F4) / API 609 / ANSI B16.10 Profile seal on disk and shaft seals of EPDM or NBR Leak tight in both directions Bolts, nuts and washers of SS A4 (in contact with Soft sealing medium), all other external fasteners of SS A2 Double-eccentric disk Corrosion protection of all cast parts by means Chambered T-sectional profile seal on the disk, of fusion bonded epoxy powder coating adjustable and exchangeable without removing (average thickness 250 microns) the disk Enclosed disk bearings Other materials for shafts, shaft bearings, seals Dry shaft design and miscellaneous accessories as well as coating Basic version equipped with self locking worm thicknesses available on request. gearbox with adjustable endstops and mechanical position indicator on the gearbox cover Gearbox with raised protection for buried application available as an option Double-eccentricity On the basis of the double-eccentric bearing of the valve disk the profile seal lifts off from the seat when starting the rotary movement. Thus no shear stresses between seat and profile seal arise (ecc.1). The bearing of the shaft stubs behind the seal section enables the use of an endless seal on the disk which provides a perfect sealing and functionality (ecc.2). Exz.1 • Best possible closing of the sealing into the body seat • Reduced operating force with perfect sealing function • Long life due to low wear of the sealing ring • Relief of the sealing ring in open position Exz.2 Drive Options for Flanged Butterfly Valves 06 2021410 /-16 /-25 Flanged Butterfly Valve with gearbox and handwheel PN10/16 (DN80 – DN2400) PN25 (DN80 – DN1000) 06 2041410 /-16 /-25 Flanged Butterfly Valve with quarter-turn pneumatic-actuator PN10/16 (DN80 – DN2400) PN25 (DN80 – DN1000) 06 2031410 /-16 /-25 Flanged Butterfly Valve with gearbox and multi-turn electric-actuator (On/Off or modulating duty) PN10/16 (DN80 – DN2400) PN25 (DN80 – DN1000) 06 2181410 /-16 /-25 Flanged Butterfly Valve with gearbox (buried version) and extension spindle PN10/16 (DN80 – DN2400) PN25 (DN80 – DN1000) 06 1 2 Drive shaft connected with the disk accurately by means of double taper pin. Due to generously dimensioned bearings the shafts are not in contact with the medium, all transitional areas safely sealed by means of O-rings. 1 3 2 4 3 4 Dynamic sealing of the drive shaft by means of O-rings in double safety design, bearing bushings of selflubricating Bronze guarantees a safe and long life time. Endless closure sealing of loadable elastomer in special T-profile attached to the disk by means of a one-piece retaining ring, exact pre-load and securing by means of fixing bolts and counter pins guarantee safe operational leak-tightness.
