Pneumatic sab hauv xov pob valve muaj ob (lossis ib leeg) ua yeeb yam pneumatic piston actuator thiab ib qho xov hauv pob valve. Lub cev valve tuaj yeem muab faib ua ib qho, ob-thooj, lossis peb-thooj hom. Lub rooj zaum valve txais cov qauv kev sib khi elastic rau kev ruaj ntseg sealing thiab yooj yim qhib thiab kaw. Lub qia valve siv cov qauv qis-loaded nrog inverted sealing los tiv thaiv kev cuam tshuam thaum lub sij hawm txawv txav hauv lub valve kab noj hniav. Lub pneumatic actuator ntiav cov ntaub ntawv tsis tshua muaj kev sib txhuam rau lub tes tsho bearing, thiab sab hauv thiab sab nrauv ntawm lub tog raj kheej lub cev tau txais kev kho mob nyuaj anodized los tiv thaiv corrosion, cuam tshuam rau lub tog raj kheej txoj kev pab cuam lub neej. Cov khoom no muaj kev ua haujlwm ruaj khov thiab pom cov ntawv thov dav hauv cov haujlwm xws li petrochemicals, metallurgy, hluav taws xob fais fab, lub teeb kev lag luam, tshuaj, thiab lwm yam.
