I-Pneumaticivalvu yebhabhathaneluhlobo lwevalvu elawulayo esetyenziswa kakhulu kwiipayipi zoshishino. Icandelo layo eliphambili yidiski emile okwediski efakwe kumbhobho kwaye ijikeleza kwi-axis yayo. Xa idiski ijikeleza ii-degrees ezingama-90, ivalvu iyavalwa; Xa ijikeleziswa ii-degrees ezi-0, ivalvu iyavuleka.

Umgaqo osebenzayo wevalvu yebhabhathane yentsimbi engagqwaliyo ephefumlayo kukulawula ukujikeleza kweplate yebhabhathane nge-actuator yomoya. I-actuator yomoya ifumana umoya ocinezelweyo njengomthombo wamandla, kwaye iqhube iplate yebhabhathane ukuba ivuleke okanye ivale ngokweemfuno zesignali yokulawula. Le ndlela yokuqhuba yenza ivalvu yebhabhathane ephefumlayo ibe neengenelo zesantya sokuphendula ngokukhawuleza, ukuchaneka okuphezulu kokulawula, ukusebenza okulula njalo njalo.

Iivalvu zebhabhathane ezisebenzisa umoya zisetyenziswa kakhulu kwiindawo zoshishino. Zisetyenziswa kakhulu ukulungisa isantya sokuhamba kunye noxinzelelo lwendlela ephakathi, kunye nokufezekisa ukunqunyulwa kunye nokudibanisa umbhobho. Ngenxa yesakhiwo sayo esilula, ubungakanani obuncinci kunye nobunzima obulula, ivalvu yebhabhathane engaqhelekanga esebenzisa umoya inamandla okuhamba kakuhle kwinkqubo yombhobho, nto leyo enokunciphisa ukumelana nolwelo kunye nokusetyenziswa kwamandla. Ukongeza, ivalvu yebhabhathane ye-pneumatic 4 Inch ikwanawo amandla okugqwala kunye nokumelana nobushushu obuphezulu, kwaye inokuziqhelanisa neendawo ezahlukeneyo ezinzima.

Iivalvu zebhabhathane ezisebenzisa umoya zisetyenziswa kwiindawo ezininzi zoshishino, ezifana ne-petrochemical, umbane, i-metallurgy, amayeza, ukutya njalo njalo. Kwishishini le-petrochemical, iivalvu zebhabhathane ezisebenzisa umoya zihlala zisetyenziswa kwinkqubo yemibhobho yeoyile ekrwada, ioyile ecociweyo, izinto ezikrwada zeekhemikhali kunye nezinye izinto ezisetyenziswayo. Kwishishini lombane, iivalvu zebhabhathane ezisebenzisa umoya zisetyenziswa kakhulu kwimibhobho yokuhambisa amanzi abandayo, igesi yepetroli kunye nezinye izinto ezisetyenziswayo kwizityalo zamandla. Kwishishini le-metallurgical, iivalvu zebhabhathane ezisebenzisa umoya zisetyenziswa kwiinkqubo zemibhobho ezineentsimbi ezinyibilikisiweyo ezinobushushu obuphezulu kunye nezinye izinto ezisetyenziswayo.

Ngamafutshane, ivalvu yebhabhathane ephefumlayo idlala indima ebalulekileyo kwinkqubo yemibhobho yemizi-mveliso ngesakhiwo sayo esahlukileyo kunye nomgaqo wokusebenza. Ayinakufikelela kuphela kulawulo oluchanekileyo lokuhamba komoya kunye noxinzelelo oluphakathi, kodwa ikwanayo nokumelana okuhle nokugqwala kunye nokumelana nobushushu obuphezulu, ngoko ke isetyenziswa kakhulu kwiinkalo ezahlukeneyo zoshishino.
