The Core of Our <strong>Valves</strong>The core of the <strong>Flowrox</strong> pinch valve is the elastic sleeve, which is the only part in contact withthe medium. The full bore sleeve integrates the valve to the pipeline. This full bore designeliminates turbulence and minimizes pressure losses.Technologically advanced <strong>Flowrox</strong> sleeves guaranteehigh wear and corrosion resistance, a trouble freeoperation, and extended lifetime. The sleeve isa reinforced construction making it the pressurecontaining part of the valve. Standard <strong>Flowrox</strong> sleevesfor dual pinching are equipped with opening tags toensure full valve opening in all conditions.Special sleeve design options include:• a conical sleeve for control valves• a vacuum sleeve for negative pressure applications• SensoMate sleeve detecting and signalling criticalwear• polyurethane lined sleeve with improved protectionagainst wearOpening tagsReinforcingcordsWear-resistantinner liningTo cover a wide range of applications, several rubberqualities are available.SLEEVE MODEL SELECTION Example: SBRT10300/750/3L2SBRT10 300 / 750 / 3 L 2SLEEVE MATERIALPRESSURESLEEVE SLEEVEINNER / LENGTH /SHAPE OF OPENING FLANGECLASS (PN) DIA (mm) (mm)FLANGE TAGS DRILLINGSSBRT = Styrene butadiene 1 = 1 bar25 - 1000 Depends ontype 1L = opening 1 = –the sleevetagsEPDM = Ethylene propylene 6 = 6 barinner diameter type 32 = DIN PN 10NR = Natural rubber10 = 10 bartype 43 = DIN PN 16NBR = NitrileCSM = Hypalon16 = 16 bar25 = 25 barDetermined bythe valvemanufacturer4 = DIN PN 255 = DIN PN 40EPDMB = Green liquor sleeveCR = ChloropreneIIR = ButylNRF = Foodstuff naturalrubberNBRF = Foodstuff nitrileHNBR = Hydrogenated nitrileFPM = Fluorine rubber40 = 40 bar64 = 64 bar100 = 100 bar(dependingon the valvediameter/pressure class)6 = ANSI 1507 = ANSI 3008 = BS TABLE D9A = AS TABLE D9B = AS TABLE E9C = JIS 109D = JIS 169 = OTHERPU = Polyurethane/M = <strong>Flowrox</strong> SensoMatesleeve/PU = PU-coating inside thesleeve/VAC = Vacuum sleeve6
