Düker - Butterfly Valves - Brochure

1Butterfly Valves Made of Ductile Cast Iron DN 100 - DN 1200for water and gas supply pipelines FIttINgs aND ValVesIn Germany alone, many thousands of kilometres of pipelines ensure that water is at our disposal every-where and anytime.The pipeline materials used for this purpose have to fulfil high demands:• resist to any ground movements• work reliably for years• remain impeccably hygienic• transport our drinking water safely and loss-freeIt all Depends on the MaterialCast iron as a natural material is the basis of all Düker valves. Due to its excellent material characte-ristics, it fulfils these requirements completely:• longevity• water tightness• good corrosion resistance• economy• and last but not least 100% recyclability Düker Butterfly ValvesOur butterfly valves are used both for drinking water and raw water and for all gas types (including pressurized air). On request, the butterfly valve may also be used for different media.Nominal pressures are PN 10, PN 16 and PN 25, with the maximum ope-rating and differential pressure being equal to the nominal pressure. The flanges are in accordance with the DIN standards 28604, 28605 or 28606. Flanges as per ASA and BSI are available on request. The maximum operating temperature for water is 60 °C. The indications for gas follow G 260 / I. execution of the DiscThe Düker butterfly valves have a flow-optimised, double-eccentric disc. The profile sealing can easily be adjusted and changed. The shaft bearings run in maintenance-free bush bearings. The shafts are sealed through O-rings inside and outside. On the gear box cover, there is an open/closed indication. The end stop “closed“ of the gear can be adjusted. The driving can be done with handwheel, an adapter as per GW 366, with an elec-tric actuator, and with hydraulic or pneumatic actuators.2 3etec enamel – a compound material which forms an inseparable, chemical bond with the base ma-terial ductile cast iron, convinces due to: • corrosion protection inside and outside up to soil class III• high resistance against mechanical stress (friction, impact, pressure, thrust)• resistance to ageing• no diffusion of water through the coating, which might cause blisters between the base material and the coating• safety against penetration under the coating even in case of local damages to the surface• resistance to climate and medium (UV radiati-on, humidity, temperature, organic solvants)etec enamel – ths special all aroundsurface protection for Düker butterfly valvesDüker Butterfly Valves – safe, Flow-optimised and ResistantPermanent Protection all aroundIn order to ensure an even better and permanent protection against corrosi-on and incrustation, our butterfly valves are enamelled as a standard coating.Up to DN 600, the butterfly valves are enamelled inside and outside; above DN 600 they are enamelled inside.Bacteria cannot attach themselves to the smooth enamel surface. Therefore, the adhesion of biofilms is actively avoided, which guarantees absolutely safe drin-king water supply – even in case of varying temperatures.Flow-Optimised DiscThe Düker butterfly valves have a flow-optimised disc with double-offset journal. This bearing causes a slight rotation at the moment of opening and clo-sing the valve, which is in addition superimposed by Optimised gear BoxAs an option, our gear boxes have the following driving modes:• handwheel with ball knob• electric actuator• stem extension with wheel type indicator• stem extension without wheel type indicatorThe Düker gears with slidercrank mechanism have proven themselves for years and are adapted opti-mally to the Düker butterfly valve.At a uniform initial revolution speed, the closing speed decreases, so the gear clo-ses softly. This mechanism reduces or eli-minates pressure peaks.The gear box is chambered watertight and cor-responds to the degree of protection IP 68.The mechanical position indication (open/closed) is situated on the gear box below a transparent plas-tic cover and is linked directly to the shaft.special VersionsSpecial versions are possible on request - for example: butterfly valves with three-point locking device for prevention of accidents during mainte-nance or revision work. Please consult us.Wear-Resistant Bearing and Driving shaftThe bearing sleeves made of bronze are highly wear-resistant and show an excellent behaviour regarding surface pressure and friction coefficients.The driving shaft and bearing journal made of stainless steel are chambered medium-free thanks to a newly developed sealing configuration between the bearing lug of the disc and the bearing sleeve. The connection between the disc and the shaft is through a square plug connec-tion. In combination with the bronze material of the bearing sleeve, this square plug connection ensures a safe and easy operability.easily Replaceable sealing RingThis disc sealing, a profile ring, is a resilient-sealing loop, which runs alongside the shaft axle and seals directly on the smooth enamel. It is fixed to the disc with a retaining ring. The profile ring with one-piece retaining ring ensu-res a uniform and controlled pre-tension, which al-lows the sealing to be exchanged without problems in the “open“ position. a translatory motion. Therefore the disc separates from the housing at only a slight degree of opening, which relieves the sealing safely.4 5Butterfly Valves type 4510 and 451 – the esse ntial advantagesResistance values (zeta values) in open positionDN type zeta-value100 4510 0.80150 4510 0.75200 4510 0.70250 4510 0.67300 4510 0.65350 4510 0.62400 4510 0.60500 4510 0.55600 4510 0.50700 451 0.47800 451 0.45900 451 0.421000 451 0.401200 451 0.356 7Butterfly Valves type 4510 and 451 – Materials and VersionsDetails and MaterialsVersionsitem description material item description material1 Body EN-GJS-400-15 18 washer A22 Disc EN-GJS-400-15 19 threaded sleeve lower part X20Cr133 Retaining ring EN-GJS-500-7 20 threaded sleeve upper part X20Cr134 Shaft X20Cr13 21 headless screw A25 Bearing journal X20Cr13 22 O-ring NBR6 Bearing sleeve A GZ-CuSn7SnPb 23 cylinder pin Cq22, Cq357 Bearing sleeve B GZ-CuSn7SnPb 24 washer bush POM8 Sealing ring PE 100 25 countersunk screw A29 O-ring NBR 26 O-ring NBR10 Sealing EPDM 27 countersunk screw A211 Profile sealing EPDM 28 countersunk screw A212 Blind pin PA6GF30 29 countersunk screw A213 Connection ring module PA6GF30 30 safety ring Ck 7514 O-ring NBR 31 gearbox SK I/II B EN-GJS-500-715 O-ring NBR16 O-ring NBR17 Hexagonal screw A2 Other materials on requesttype DN PN flanged long with bypasslong without bypassNovo socketsetec enamel inside and outsideinside emamel, outside 2-components epoxy paint 4510 100 10-25 • •4510 125 10-25 • •4510 150 10-25 • • •4510 200 10-25 • • •4510 250 10-25 • • •4510 300 10 • • • • •4510 300 16 • • • • •4510 300 25 • • •4510 350 10-25 • •4510 400 10 • • • • •4510 400 16 • • • • •4510 400 25 • • •4510 500 10 • • • • •4510 500 16 • • • • •4510 500 25 • • •4510 600 10 • • • •4510 600 16 • • • •4510 600 25 • •451 700 10 • • • •451 700 16 • • • •451 700 25 • •451 800 10-16 • • • •451 900 10-16 • • • •451 1000 10-16 • • • •451 1200 10-16 • •8 9 10Butterfly Valves with our without Handwheelmodel nominal dimension DN in mmnominal pressurePN in barlengthl in mmflangeø D in mmfoot dimensionB in mmheighth1 in mmdimensiont1 in mmdimensiont2 in mmdimensionx1 in mmgearsK4510 100 10/16 190 220 120 116 110 258 65 I B4510 100 25 190 235 120 121 110 258 65 I B4510 125 10/16 200 250 130 131 122 270 65 I B4510 125 25 200 270 130 141 122 270 65 I B4510 150 10/16 210 285 150 149 138 286 65 I B4510 150 25 210 300 150 157 138 286 65 I B4510 200 10 230 340 160 177 175 311 65 II B4510 200 16 230 340 160 177 175 311 65 II B4510 200 25 230 360 160 187 175 311 65 II B4510 250 10 250 400 180 208 212 348 65 II B4510 250 16 250 400 180 208 212 348 65 II B4510 250 25 250 425 180 220 212 348 65 II B4510 300 10 270 455 200 233 221 371 65 II B4510 300 16 270 455 200 233 221 371 65 II B4510 300 25 270 485 200 248 221 371 65 II B4510 350 10 290 505 225 259 287 426 65 II B4510 350 16 290 520 225 269 287 426 65 II B4510 350 25 290 555 225 287 287 426 65 II B4510 400 10 310 565 300 294 307 446 65 II B4510 400 16 310 580 300 294 307 474 100 III4510 400 25 310 620 300 319 307 474 100 III4510 500 10 350 670 350 350 377 524 100 III4510 500 16 350 715 350 372 377 524 100 III4510 600 10 390 780 320 401 442 614 100 III4510 600 16 390 840 330 431 442 673 160 IV4510 600 25 390 845 400 431 442 693 160 IV451 700 10 430 895 400 450 549 665 150 IV451 700 16 430 910 400 460 549 665 150 IV GZ451 700 25 430 960 450 485 549 665 150 IV GZ451 800 10 470 1015 450 510 594 710 150 IV GZ451 800 16 470 1025 450 515 594 710 150 IV GZ451 900 10 510 1115 550 560 634 750 150 IV GZ451 900 16 510 1125 550 568 634 740 200 GS 200 GZ451 1000 10 550 1230 600 620 699 815 150 IV GZ451 1000 16 550 1255 600 630 699 805 255 GS 250 GZ451 1200 10 630 1455 700 730 828 903 255 GS 250 GZ451 1200 16 630 1485 700 750 828 903 255 GS 250 GZheighth2 in mmstemø d in mmweightca. kg223 20 32223 20 33223 20 37223 20 38223 20 43223 20 43223 20 55223 20 55223 20 60223 20 74223 20 73223 20 80223 20 91223 20 96223 20 104223 20 115223 20 122223 20 144223 20 148278 20 190278 20 214278 20 244278 20 274278 20 346403 30 500403 30 531403 30 645403 / 465 30 / 20 663403 / 465 30 / 20 748403 / 465 30 / 20 900403 / 465 30 / 20 915403 / 465 30 / 20 1198465 20 1261403 / 465 30 / 20 1488568 20 1655568 20 2065568 20 2135heighth2 in mmhandwheelø d1 in mmweightca. kg325 200 33325 200 34325 250 38325 250 39325 250 44325 250 44325 250 56325 250 56325 250 61325 250 75325 250 74325 250 81325 250 92325 250 97325 250 105325 250 116325 250 123325 250 145325 250 149315 315 192315 315 216315 315 246315 315 276315 315 348500 500 506500 500 537570 500 650745 400 665745 400 750745 400 902745 400 917745 400 1200675 400 1263745 400 1490715 640 1660715 640 2070715 640 2140 h2 d1 disc type 451disc type 4510Basic version without handwheel with handwheelPlease note: for the underground installation we supply butterfly valves with height-adjustable telescope stem extension sets in various lengths.

The bypass normally contains its own shut-off valve and is dimensioned to one tenth of the main nominal dimension. The length of the standard butterfly valve is increased in order to install the bypass, to the length as per EN 558 series 15 (F15).the bypass has two main advantages:• the supply pipelines can be filled slowly for efficient air release• the valves, which are under pressure from one side, can be operated without requiring elevated force. The required pressure equalisation is carried out via the bypass.

While the water flows, both valves remain open. The process is applied vice versa when closing the valves: First the main valve, then the bypass valve is closed. Air vent problems and pressure peaks do not pose a problem in this procedure. disc type 451disc type 4510Basic long version with bypass** long version without bypass on request16 17type nominal dimensionDN in mmnominal pressurePN in barsocketø D in mmlengthete in mmlengthl in mmfoot dimensionB in mmheighth1 in mmheighth2 in mmdimensiont1 in mmdimensiont2 in mmgearsK4510 150 10 - 25 216 106 360 150 147 300 177 231 I B4510 200 10 - 25 271 111 383 160 175 300 202 256 II B4510 250 10 - 25 324 116 398 180 205 300 248 300 II B4510 300 10 - 25 381 121 413 200 230 380 263 317 II B4510 400 10 - 25 489 172 472 250 285 380 328 382 III4510 500 10 - 25 598 205 527 300 340 400 370 465 IIIThrust-resisting connections of ductile iron but-terfly valves with pipes made of PEHD plastic are possible in the nominal dimensions DN 150 up to DN 200. Quality ManagementWe apply high requirements on the quality of our products. Therefore, as early as in 1993, we introduced a modern quality management system as per EN ISO 9001, which is certified by TÜV CERT. Furthermore our products are tested and approved according to numerous other product or market-specific standards and regulations.For some products, in the framework of quality protection associations, we vo-luntarily observe criteria that surpass the standard requirements by far.Regular and random tests, internal and external audits, but also our staff‘s motivation ensure that the QM system, as an integral part of the overall orga-nisation, is permanently developed. This means, also for the future, that we supply products which convince through their longevity and are up to the latest state of the art.Quality on the Highest levelDüker valves are used worldwide and are subject to elevated requirements in the drinking water sector. Therefore each valve is tested with extreme care before it leaves the factory. It goes without saying that the requirements of the DVGW worksheet W 270 “Reproduction of microorganisms on materials for the drinking water sector – tests and evaluation“ are observed.Butterfly Valves with Novo sockets18FIttINgs aND ValVesDRaINage teCHNOlOgYeNgINeeRINgglass lININg teCHNOlOgIesJOBBINg FOUNDRYDüker gmbH & Co.
