NeoSealWafer, lugged and double flanged lined butterfly valves DN 40-900NEOTECHAA PTFE lined solution according ISO 5752/5 short(EN 558-1/T5) with various corrosion resistant discmaterials to satisfy demanding customer requirementsFeatures One of the most important features is thestem seal.The pressure to keep the two sealingsurfaces together is provided by anupper and lower set of Belleville springsresulting in a superior stem seal, which isTA-Luft / VDI 2440 approved. The elastomer back-up pads behind theliner ensure a tight fit around the disc, fora bubble tight shut-off. The liner provides a wide flange sealingsurface. A one piece thin disc stem lined with3 mm molded PFA providing high Kvvalues. The liner and disc are the only two valveparts in contact with the medium. Primary shaft sealing by preloadedcontact between disc and liner hub. Secondary shaft seal by oversizing theshaft diameter in relation to the shafthole in the liner. The liner and disc are molded andmachined to close tolerances to provide:- low torque- less stress and deformation duringopening and closing Vacuum tests with helium with pressuresless than 20 Pa absolute (0.2 mbarA). Optional TFM lining available forextremely demanding applications. Integral body locating holes to ensureperfect centering of the valve. Actuator flange and stem dimensionsacc. ISO 5211. Anti blow-out proof shaft.Technical dataGeneral applicationPressure (bar)The valves are ideally suited for corrosiveapplications, requiring reliable performance,tight shutoff, constant torque and nomaintenance. The valves successfullyhandle a multitude of corrosive applicationsin industries such as chemical, petrochemical, pulp and paper, semiconductor(UPW), foundries and mining.The accurate machining of all valvecomponents, and the combination ofsafety precautions in the shaft area providea drop-tight seat sealing and a positivegastight shut-off through the shaft area toatmosphere.: 10 (DN 40-600) 6 (DN 700, DN 800and DN 900)2.5 (DN 750)Temperature ( C): -40 to 200Sizes (mm): 40-900Flange accommodation : DIN PN 10/(16) ANSI 150, JIS 10KBubble tight shut-off in both directions,in accordance with EN-12266-1 leakrate A(UHMWPE leakrate B).www.pentair.com/valvesPentair reserves the right to change the contents without notice NEOJV-0003-EN-1305
NeoSealWafer, lugged and double flanged lined butterfly valve DN 40-900 Top flange according to ISO 5211, simplifiesthe actuator mounting. Conductive Iglidur bearing. Split body made of ductile iron (DIN 0.7043)with polyester coating. Integral body locating holes to ensureperfect centering of the valve betweenflanges. Self lubricating bearings. An upper and lower set of Belleville discsprings exert uniform loading through thepusher, pressing the PTFE liner and theshoulder of the disc hub together resultingin a leak free mechanical stem seal. One piece disc-stem allows a thinner wafer,resulting in a higher Kv value. Resilient elastomer back-up pads provide anuniform pressure onto the circumference ofthe disc ensuring a bubble tight valve underall operating conditions. Precision PFA encapsulation, 3 mm thick,bonded and interlocked to the one piecedisc-stem. Suitable for full vacuum at fullrated temperature.

By using the NeoSeal wide face-to-face version,the disc chord dimension Y is reduced to prevent contact between the disc and the pipe. Typically,full bore PTFE spacers are used to eliminate interference between the disc and I.D. of the pipe,however, spacers can introduce additional emission paths, maintenance issues due to cold flow,and thermal expansion and contraction. The wide face to face Neoseal eliminates the need for PTFEspacers thus minimizing emissions to atmosphere and maintenance.Pentair reserves the right to change the contents without notice page 5
