Tag nrho- pob valves ua tiav qhov qhib thiab kaw nrawm los ntawm kev tig 90 degree, nrog cov dej ntws tsawg, ua rau lawv tsim nyog rau kev ua haujlwm nquag thiab kev tu cov kav dej; Lub rooj vag li qub tswj kev qhib / tawm los ntawm kev nce thiab txo lub rooj vag, qhib thiab kaw maj mam, nrog kev khiav qis dua tab sis yuav tsum tau siv zog ntau rau kev khiav lag luam, thiab feem ntau yog siv rau kev sib cais tseem ceeb uas qhib tag nrho lossis kaw tag nrho rau lub sijhawm ntev.
Tag nrho- pob valvestau dav siv hauv cov kav dej loj kaw-tawm, kev sib cais thaum muaj xwm txheej ceev, thiab cov kav dej ntxuav hauv kev lag luam xws li roj av, roj av, thiab kev kho dej vim lawv qhov zoo xws li tsis tshua muaj dej tsis kam, qhib thiab kaw ceev, thiab yooj yim ntawm automation.
Rooj vag li qub, ntawm qhov tod tes, feem ntau yog siv nyob rau hauv loj - txoj kab uas hla lub ntsiab kav dej huv si xws li dej, kua, ncu, thiab roj, vim lawv cov qauv yooj yim, tsis tshua muaj nqi, thiab txhim khu kev qha sealing, raws li kaw- tawm li qub rau kev saib xyuas kev rho tawm lossis ntev - lub sijhawm ua haujlwm, thiab lawv ua haujlwm ruaj khov, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias.

FAQ
Thaum twg siv lub pob tag nrho lub pob valve?
Vim tias lawv muaj qhov tsawg kawg nkaus tsis kam ntws, tag nrho cov chaw nres nkoj pob li qub tau pom zoo rausystems nyob rau hauv uas ob qho tib si solids thiab kua ntws los ntawm lub li qub. Kev tsim qauv qhib txo qhov muaj peev xwm ntawm kev tsim- sab hauv thiab ib ncig ntawm lub valve txuas, uas tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm lub valve dhau sijhawm.
Dab tsi yog tus yam ntxwv ntws ntawm qhov chaw nres nkoj puv pob valve?
Txoj kev ntws nyob rau hauv rooj plaub ntawm qhov chaw nres nkoj puv pob valve yogyuav luag zoo li cov yeeb nkab ncaj nraim (nyob ntawm lub sijhawm ntawm cov yeeb nkab) nrog tus ID ntawm lub pob sib piv cov yeeb nkab ID. Yog li qhov kev pab cuam los ntawm cov yeeb nkab seem yuav yog qhov tseem ceeb piv rau tsuas yog lub pob hauv cheeb tsam hauv siab poob vim kev sib txhuam.
