American Standard rooj vag valve plays lub luag hauj lwm ntawm kev txiav tawm los yog txuas cov nruab nrab hauv lub raj xa dej, thiab tuaj yeem ua haujlwm zoo hauv qhov chaw nres tsheb thermal, roj av, tshuaj lom neeg, thiab lwm yam kev ua haujlwm hauv cov kav dej nrog qhov kub ntawm -29 degree {{1 } } degree , thiab qhov nruab nrab tuaj yeem yog roj, dej, chav dej, thiab lwm yam. Cov qauv ntev thiab cov yam ntxwv ntawm American Standard gate valve feem ntau yog raws li hauv qab no:
1. American Standard rooj vag valve ua tau raws li tus txheej txheem ntawm kev tsim cov txheej txheem siab heev hauv tsev thiab txawv teb chaws, nws cov sealing kev ua tau zoo, thiab cov duab zoo nkauj thiab dav. American Standard rooj vag li qub feem ntau siv cov ntaub ntawv uas tsis yog xim hlau.
2. Cov qauv siv nyob rau hauv lub rooj vag valve yog ib tug wedge-type resilient rooj vag qauv nrog rau nruab nrab thiab loj-inch teem dov bearings, nrog rau qhov zoo ntawm kev sib txhuam tsis tshua muaj, thiab yooj yim rau qhib thiab kaw.
3. Lub rooj vag thiab lub rooj zaum sealing nto yog ua los ntawm steely cobalt carbide overlay vuam los yog hlau-raws li alloy overlay welding, nrog rau kub-resistant, corrosion kuj, abrasion tsis kam, thiab kev pab lub neej ntev.
4. American standard gate valve stemS tom qab tempering thiab nto nitriding kev kho mob, muaj zog hnav thiab puas kuj thiab corrosion kuj.
5. tuaj yeem siv ntau yam ntawm cov kav dej flange qauv thiab flange sealing nto hom, kom tau raws li qhov xav tau ntawm ntau yam haujlwm thiab cov neeg siv khoom xav tau.
