Cov yam ntxwv tseem ceeb ntawm Resilient Seated Non-Rising Stem Gate Valve
Compact Vertical Footprint
Lub qia rotates nyob rau hauv ib qhov siab ruaj, ua subterranean thiab vault installation yooj yim yam tsis tas yuav tsum tau overhead clearance.
Zero-Leakage Rubber Wedge
High-ductility hlau core vulcanized nrog EPDM los yog NBR roj hmab tsim ib lub foob kaw ntom nti txawm nyob rau hauv cov kav dej nqa lub teeb tshem tawm cov khib nyiab.
Unobstructed Full Passage
Nqa lub rooj vag tag nrho tawm ntawm txoj kev ntws thaum qhib, txo qhov kev sib txhuam tsis zoo thiab tso cai rau cov cuab yeej ntxuav inline kom dhau mus.
Durable Epoxy Shield
Electrostatic fusion-pab pawg epoxy tiv thaiv qhov chaw sab hauv thiab sab nrauv tiv thaiv cov av noo, tshuaj lom neeg, thiab xeb.
Siab -Tshwj xeeb cov ntsaws ruaj ruaj
Ntau O-Nplhaib qia ntsaws ruaj ruaj tso cai rau kev tu lub sijhawm ua haujlwm nyob rau hauv lub raj xa dej siab, tiv thaiv lub sijhawm tsis tau teem sijhawm.
Tsawg Ua Haujlwm Torque
Tus kheej -lubricating tooj liab alloy qia txiv ntoo thiab tiv thaiv - txhuam txhuam kom ua haujlwm zoo ntawm lub log hla ntau txhiab lub voj voog.
Lub Valve ua haujlwm li cas
Lub valve txhais torque rotational los ntawm lub log khiav mus rau hauv lub rooj vag tawm mus ncig uas siv cov qia threading:
Qhib:Tig lub qia txee -clockwise rub cov roj hmab-coated wedge upwards rau hauv lub kaus mom, qhib tag nrho cov kav dej bore rau unobstructed ntws.
Kaw:Tig clockwise tsav lub wedge downward. Lub elastomeric nto compresses tawm tsam lub cev sab hauv phab ntsa kom kaw cov dej ntws ruaj ntseg.

Cov ntawv thov tseem ceeb ntawm Resilient Seated Non-Rising Stem Gate Valve
Kev faib tawm dej
Muab kev sib cais huv si hauv cov chaw hauv nroog, cov chaw kho mob, thiab cov kab sib faib siv cov txheej txheem kev nyab xeeb, muaj ntawv pov thawj.
Nthuav Underground Vaults
Fits yooj yim rau hauv subterranean chambers thiab trenches qhov twg ntsug clearance txwv tsis pub nce qia li qub.
Kev tswj dej khib nyiab
Resistant cov dej phwj nyoos, av nkos, thiab cov organic sediment buildup los ntawm kev sib khi ua haujlwm ntawm lub ntsej muag tawv tawv.
Hluav Taws Mains thiab Kev Tiv Thaiv
Muab cov kev sib cais ruaj khov rau cov kab hluav taws xob tua hluav taws, lub nplhaib sib txuas, thiab siab - cov twj tso kua mis.
Industrial Utility Loops
Tswj cov cua txias, cov kab dej nyoos, thiab HVAC dej circuits thoob plaws cov chaw tsim khoom lag luam.

FAQ
Q: Vim li cas thiaj xaiv lub rooj vag rooj vag uas muaj zog dua lub rooj zaum hlau tsoos?
A: Resilient seated li qub siv cov roj hmab hloov tau yooj yim -coated wedge uas ua npuas - nruj seal tiv thaiv lub cev du phab ntsa. Lawv tshem tawm cov rooj zaum hauv qab qhov chaw uas grit accumulates, tiv thaiv kev puas tsuaj hauv cov dej qias neeg.
Q: Lub valve puas tuaj yeem ntsia tau kab rov tav lossis ntsug?
A: Yog. Nws ua haujlwm zoo hauv kab rov tav thiab ntsug. Rau qhov ntau thiab tsawg (DN350 thiab saum toj no) mounted kab rov tav, ntxiv ib lub gearbox los yog sab hauv wedge qhia pab tswj kev sib dhos thiab ua haujlwm yooj yim.
Q: Kuv yuav xaiv li cas ntawm EPDM thiab NBR wedge roj hmab?
A: Xaiv EPDM rau cov dej haus, HVAC circuits, thiab cov kab hluav taws xob dav dav. Xaiv NBR yog tias qhov nruab nrab muaj cov kab mob hydrocarbons, roj, lossis cov khoom siv dej khib nyiab.
Q: Lub valve no puas tuaj yeem siv rau kev tswj xyuas tas li?
A: Tsis yog. Rooj vag li qub yog tsim los rau kev sib cais (tag nrho qhib lossis kaw tag nrho). Throttling nyob rau hauv ib feem qhib lub xeev ua rau cov dej tshaj tawm vibrate thiab hnav down elastomeric wedge.
Q: Puas yog txheej txheej sab hauv muaj kev nyab xeeb rau cov dej haus?
A: Yog. Tus txheej txheem tsis yog- lom, electrostatic fusion- khi epoxy hmoov txheej (yam tsawg 250 microns) ua raws li cov cai tseem ceeb thoob ntiaj teb kev nyab xeeb dej haus.
Q: Puas tuaj yeem stem O-rings hloov tau raws li kab siab?
A: Yog. Nrog lub valve tig mus rau nws txoj haujlwm qhib tag nrho, lub nraub qaum - lub rooj tsim tso cai rau sab saum toj O- lub nplhaib hloov yam tsis siv lub raj xa dej loj tawm ntawm kev pabcuam.
