Product Overview
Lub Hwj Chim Hlau Tsis yog-Rising Stem (NRS) Gate Valve yog tsim los rau hnyav-cov kav dej sib cais hauv qhov chaw- txwv kev teeb tsa. Nws lub hauv paus kev npaj ua kom zero ntsug mus ncig thaum lub sijhawm ua haujlwm, ua rau nws zoo tagnrho rau cov trenches ntiav, faus tes hauj lwm, thiab compact valve vaults.
Ua los ntawm siab -lub zog hlau ductile (GGG50 / ASTM A536), lub valve no zoo tiv thaiv cov kav xa dej bending kev ntxhov siab thiab dej rauj. Featuring ib tug EPDM encapsulated resilient wedge thiab tag nrho - bore flow passage, nws muab bi-directional zero- leak shutoff rau cov dej hauv nroog, dej phwj tuaj, thiab industrial utility pipelines.

Cov yam ntxwv tseem ceeb ntawm Cov Hlau Hlau Tsis yog-Rising Stem Gate Valve
Compact Vertical Footprint:Txhim kho qhov siab ua haujlwm haum yooj yim rau hauv qhov chaw - txwv tsis pub cov vaults.
Siab -Lub Hwj Huam Hlau Lub Cev:Superior tensile zog tiv thaiv lub cev tawg nyob rau hauv siab surges.
Bi-Directional Zero-Leakage Sealing:Cov npoo npog tag nrho ua kom muaj npuas- nruj sealing nyob rau hauv ob qho tib si ntws.
Unobstructed Full -Bore Flow:Ncaj nraim- los ntawm txoj kev dej txo qis kev poob siab thiab sediment buildup.
Ntev -Lub Sijhawm Tiv Thaiv Corrosion:Sab hauv thiab sab nraud epoxy txheej tiv thaiv cov av txhoj puab heev thiab kua dej.
Multi-Standard Compatibility:Flange drilling adaptable rau EN 1092-2, ANSI B16.1, thiab BS 4504.

FAQ
Q: Dab tsi yog cov hlau nplaum uas tsis yog - nce qia rooj vag valve?
A: Nws yog lub raj xa dej cais tawm nrog qhov ruaj khov - qhov siab qia uas tig sab hauv, tsim los rau kev sib cog lus lossis faus dej.
Q: Dab tsi yog qhov txawv ntawm NRS thiab nce qia rooj vag li qub?
A: NRS li qub tuav qhov siab tas li thaum lub sijhawm ua haujlwm, thaum nce qia li qub txav mus rau sab saud, xav tau kev tshem tawm ntsug ntxiv.
Q: Cov xov xwm twg tsim nyog rau lub valve no?
A: Nws yog qhov tsim nyog rau cov dej haus, dej tsis qab, cov dej phwj tuaj kho, thiab tsis yog - cov kua dej muaj zog nyob ntawm kev xaiv roj hmab.
Q: Cov li qub no puas tuaj yeem haum cov qauv sib txawv thoob ntiaj teb flange?
A: Yog lawm, flanges tuaj yeem laum rau EN 1092-2, ANSI B16.1, lossis BS 4504, nrog lub ntsej muag -to-face dimensions txuam EN 558-1 lossis BS 5163.
Q: Puas tuaj yeem siv tsis tau - nce qia rooj vag valve rau kev khiav throttling?
A: Tsis yog, rooj vag li qub yog tsim los rau tag nrho -qhib lossis tag nrho- kaw cais nkaus xwb. Throttling ua rau muaj kev vibration hnyav thiab hnav lub rooj zaum.
Q: Cov ntaub ntawv dab tsi yuav tsum tau txais kom tau txais cov lus qhia ntxaws?
A: Thov muab qhov loj me (DN), siab (PN/Class), tus qauv flange, nruab nrab, kev khiav hauj lwm kub, wedge roj hmab, thiab txiav txim kom muaj nuj nqis.
