Cov yam ntxwv ntawm cov concentric flange npauj npaim li qub yog qhov qia axis, npauj npaim phaj chaw thiab lub cev lub cev qhov chaw nyob hauv tib txoj haujlwm. Feem ntau, nyob rau hauv txoj cai, siv tau lub concentric npauj npaim valve yuav sim siv concentric npauj npaim valve. Vim hais tias qhov concentric npauj npaim valve tsis yog qhov yuav tsum tau muaj rau kev sib khi ua ke los yog ua haujlwm, nws yog ib qho khoom siv. Yuav kom kov yeej cov extrusion, scraping, kom ntseeg tau tias sealing kev ua tau zoo, concentric npauj npaim valve lub rooj siv roj hmab los yog PTFE thiab lwm yam ntaub ntawv elastic, yog ib tug mos mos npauj npaim valve. Qhov no ua rau concentric npauj npaim valve hauv kev siv cov kev txwv kub.
