3 Design Feature Industrial valves nrmally require wider temperature and pressure ranges, which cnventinal resilient seated butterfly valve can nt cmply, this have led t develpment f metal seated butterfly valve. NEWAY TC series butterfly valve is triple ff-set design which has a advantage f light weight, cmpact design and cst effective and lw peratin trque and can replace traditinal gate, glbe & ball valve in mst f industries applicatin. Prducts Range: Size: 3" ~ 48" Rating: ANSI 150lb ~ 600lb Temperature Range: Bdy Materials: Disc Sealing: End Cnnectin: C ~ +550 C Cast steel, Stainless steel, Ally steel Duplex steel. PTFE, Graphite laminated Wafer, ug, Duble Flange Typical applicatin: Petrchemical plant Refinery Offshre platfrm Pwer plant NG Steel Mills NEWAY TC series butterfly valve is true metal t metal seated design, featured with quarter turn, bi-directinal & zer leakage. Because f n Tefln, Vitn r ther sft seal material used, it is inherently fire safe and can cmpletely eliminate the traditinal elastmeric seating butterfly valve leakage prblem due t seat aging r defrmatin, cnsequently wear. Wide range f available bdy material selectin make this series f valve nt nly gd fr islatin service but als ideal fr mst f prcess and cntrl applicatin. 8

4 Design Feature One-Piece shaft Anti-blwut prf design, prvide psitive maximum strength. Munting pad designed per ISO 5211, easily installatin f hand levers, gear bx, pneumatic r electric actuatrs. w emissin packing Advanced braided (tp and bttm) plus 3~4 diefrmed graphite packing rings ensure less 20ppm n fugitive emissin. Disc seat design Allws field replaceable withut special tls. aminated Seal PTFE r Graphite plus metal layers, prvide an elastic tight seal. Als fire-safe is assured. Stellited seat (ptinal) Integral hardfaced, prvide lnger valve life and less maintenance. ng-length bearing Fine-machined and hardened (Nickel-plated) t reduce the stem frictin and ensure lwer trque.

It is a trque seated, prcess pressureaided frictinless seal valve, ideally suitable fr metal seated valves n high temperature, high pressure and firesafe applicatin. Befre seating After seating Internally retained Externally retained aminated Disc Seal aminated sealing is munted in the disc, easily fr maintenance and replacement. It cnsists f 3~5 flexible graphite r PTFE layers self adhere with fine machined stainless seal ring, n need traditinal phenl resin adhere jint, There is a reasnable clearance between disc seal and disc, prvide a flating resilient seal and self centering tight seal bth in lw & high temperature applicatin. Cnical angle & streamline prfile f this laminated disc is ptimized by cmputer finite element analysis t eliminate any ptential jamming as well as give a greater Cv. Zer eakage Disc-Seat sealing was achieved by trque frce evenly laded n disc laminated seal edge, which has resilient functin t assure Zer eakage in bth hydrstatic r air test per API 598. Anti-blwut shaft. Internally & Externally retained, duble times blwut prf stem design per API 609. Internal: wer end shaft is grved with Hemicycle Ring, prevent stem blwut. External: Shaft is designed with an integral cllar and was blwut prevented by gland fllwer. Inherent Fire Safe Neway triple ffset butterfly valves are all metal cnstructin and sealing, it is inherently fire safe design. Fire safe tests t API 607 were successfully perfrmed in Neway Research & Develpment labratry. 10 materials r specificatins withut ntice and free f bligatin t furnish r install such changes n prducts previuly sld.

Shaft is fully guided by shaft bearing & gland fllwer t avid any side jiggle due t line pressure thrust. b.) The packing set is pre-cmpressed and is a cmbinatin f braided graphite rings tp and bttm with die frmed flexible graphite rings between. c.) Cntrlled shaft & stuffing bx finish with Ra0.4~Ra0.8 n shaft and Ra3.2 n stuffing bx which allw a better hlding f packing ring and results in a better shaft sealing perfrmance. d.) Optinal ive aded gland flange is available fr prviding cnstant packing cmpresin t reduce fugitive emissin frm shaft seal. e.) Optinal shaft seal design per Shell MESC 77/312 & TA-uft is als available upn request. Weather prf belleville-spring washer Cmpact & light Design NEWAY series TC butterfly valve was designed per API 609, due t its cmpact & light design. It is an ecnmical replacement fr gate, glbe and ball valves.
