I-Pneumaticivalvu yebhabhathaneuhlobo lwevalvu elawulayo esetshenziswa kakhulu kumapayipi ezimboni. Ingxenye yayo eyinhloko yidiski emise okwediski efakwe epayipini futhi ijikeleza ku-axis yayo. Uma idiski ijikeleza ama-degree angu-90, ivalvu iyavaleka; Uma ijikeleziswa ama-degree angu-0, ivalvu iyavuleka.

Umgomo wokusebenza wevalvu yebhabhathane yensimbi engagqwali yomoya ukulawula ukujikeleza kwepuleti lebhabhathane nge-actuator yomoya. I-actuator yomoya ithola umoya ocindezelwe njengomthombo wamandla, futhi iqhube ipuleti lebhabhathane ukuthi livuleke noma livale ngokwezidingo zesignali yokulawula. Le ndlela yokushayela yenza ivalvu yebhabhathane yomoya ibe nezinzuzo zesivinini sokuphendula okusheshayo, ukunemba okuphezulu kokulawula, ukusebenza okulula njalo njalo.

Amavalvu ebhabhathane asebenzisa umoya asetshenziswa kabanzi emikhakheni yezimboni. Asetshenziswa kakhulu ukulungisa izinga lokugeleza kanye nokucindezela kwe-medium, kanye nokufeza ukusika nokuxhuma kwepayipi. Ngenxa yesakhiwo salo esilula, usayizi omncane kanye nesisindo esilula, ivalvu yebhabhathane engavamile esebenzisa umoya isebenza kahle ohlelweni lwepayipi, okunganciphisa ukumelana noketshezi kanye nokusetshenziswa kwamandla. Ngaphezu kwalokho, ivalvu yebhabhathane engu-4 Inch esebenzisa umoya nayo inokumelana okuhle nokugqwala kanye nokumelana nokushisa okuphezulu, futhi ingazivumelanisa nezimo ezahlukahlukene ezinzima.

Amavalvu ebhabhathane asebenzisa umoya asetshenziswa emikhakheni eminingi yezimboni, njenge-petrochemical, amandla kagesi, i-metallurgy, imithi, ukudla njalo njalo. Embonini ye-petrochemical, amavalvu ebhabhathane asebenzisa umoya avame ukusetshenziswa ohlelweni lwamapayipi kawoyela ongahluziwe, uwoyela ocociwe, izinto zokusetshenziswa zamakhemikhali kanye nezinye izinto zokusetshenziswa. Embonini yamandla, amavalvu ebhabhathane asebenzisa umoya asetshenziswa kakhulu emipayipini yokudlulisa amanzi apholile, igesi kaphethiloli kanye nezinye izinto zokusetshenziswa ezitshalweni zamandla. Embonini ye-metallurgical, amavalvu ebhabhathane asebenzisa umoya asetshenziswa ezinhlelweni zamapayipi anezinsimbi ezincibilikisiwe ezishisayo kanye nezinye izinto zokusetshenziswa.

Ngamafuphi, i-valve yebhabhathane ephefumulayo idlala indima ebalulekile ohlelweni lwamapayipi ezimboni ngesakhiwo sayo esiyingqayizivele kanye nesimiso sokusebenza. Ayikwazi nje kuphela ukufeza ukulawula okunembile kokugeleza okuphakathi kanye nokucindezela, kodwa futhi inokumelana okuhle nokugqwala kanye nokumelana nokushisa okuphezulu, ngakho-ke isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni.
