GLV504-NP25
DIN 3356 PN25 cam khwb cia steel hauv qab lub ntiaj teb valve yog qhov zoo heev hauv kev siv dej hiav txwv. Nws kev tsim kho los ntawm cam khwb cia hlau ua kom lub zog thiab kav ntev, ua rau nws tsim nyog siv rau hauv qhov hnyav thiab corrosive marine ib puag ncig. Nrog rau qhov ntsuas siab PN25, lub ntiaj teb no lub valve muaj peev xwm tuav cov tshuab dej hiav txwv siab nrog kev yooj yim, muab kev ua tau zoo thiab kev nyab xeeb.
Qhov sib ntxiv ntawm cov qauv hauv qab no txhim kho lub valve lub peev xwm los tiv thaiv thermal expansion thiab contraction, ua rau nws zoo tagnrho rau cov ntawv thov uas muaj qhov kub thiab txias, xws li cov nkoj nkoj. Lub ntiaj teb valve lub peev xwm tswj tau meej meej ua rau muaj txiaj ntsig zoo thiab raug cai ntawm cov kua dej ntawm lub nkoj, txhawb nqa ntau yam marine systems xws li cua txias, ballast, thiab roj tswj.
Nws txoj kev tsim thiab kev ua raws li DIN cov qauv ua kom muaj kev ua tau zoo thiab kev ntseeg siab hauv kev ua haujlwm hauv hiav txwv, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov tub rog nkoj nkoj thiab cov nkoj tsim khoom. Zuag qhia tag nrho, DIN 3356 PN25 cam khwb cia steel hauv qab lub ntiaj teb valve muaj cov kev daws teeb meem rau cov kev xav tau ntawm cov dej hauv kev lag luam marine, ua rau muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Qhov ntau yam tuaj yeem tsim kho kom haum rau koj daim ntawv thov, nrog rau kev tsim kho lub cev, cov khoom siv, thiab cov yam ntxwv ntxiv tau ua kom tau raws li koj cov kev xav tau. Raws li ISO 9001 tau ntawv pov thawj, peb txais yuav txoj hauv kev los xyuas kom meej qhov zoo, koj tuaj yeem paub tseeb ntawm kev ntseeg tau zoo thiab kev sib khi ua tau zoo los ntawm kev tsim lub neej ntawm koj lub cuab tam.
