Ny valve pneumatic mifehy ny valve dia valve fampisehoana dia afaka mifehy tsara ny fikorianan-drà sy ny tsindry amin'ny tsiranoka. Izy io dia manana tombony amin'ny valiny haingana, fahatokisana avo sy fampiharana be. Izy io dia ampahany tsy takatra sy manan-danja amin'ny rafi-pitantanana ny indostrialy. Ny satroka pneumatic mifehy ny valve dia valve mifehy ny valve izay mifehy ny fikosoham-bary amin'ny alàlan'ny herin'ny pneumatic.
Ireto ny endrik'izy ireo famaritana ny vokatra:
1. Ny firafitra tsotra : ny valve pneumatic dia mifehy ny valve misy valve, rakotra valve, valve iray, satroka pneumatic, sns sns.
2. Fanitsiana mialoha : ny satroka pneumatic mifehy ny valve dia manamboatra ny fifehezana pneumatic, izay mety hahatratra ny fanitsiana ny fikorianan-javatra avo lenta ary hahatonga ny ranon-tsirinina sy azo itokisana.
3. Valiny haingana : Ny fehin-kibo maloto dia ny valve mifehy ny valve dia manana ny toetran'ny valiny haingana, izay mety hanitsy haingana ny fanokafana ny valva mba hampifanarahana ny fiovana.
4. Ny fanoherana mafy , ny vatan'ny valve, ny fonon-doha ary ny singa lehibe amin'ny satroka pneumatic dia vita amin'ny fitaovana miolakolaka, izay manana fanoherana mahery vaika ary mety amin'ny media matevina.
Ny vokatra lehibe ataon'ny orinasa dia misy valve fanaraha-bazana pnematic, valve ball pnematic, valve control elektrika, fluorine voditongotra valve, precession vortex flummeter, goavambe.
