Ny endri-javatra vokatra momba ny vata fanaraha-maso pneumatic dia misy:
1. Ny fanitsiana tsara : ny valve contrecercic pneumatic dia manangana mpikatroka pneumatic, izay afaka manatanteraka fanitsiana sy fifehezana tsara sy manana fahaiza-manitsakitsaka avo lenta.
2. Valiny haingana : Ny satroka pneumatic mifehy ny valve dia manana ny toetran'ny valiny haingana ary afaka manitsy haingana ny fikorianan-javatra sy ny fanerena hampifanaraka amin'ny toe-javatra miasa isan-karazany.
3. High Relchabilit Y: Ny satroka pneumatic mifehy ny valve dia manangana mpijery tsy azo itokisana, izay manana fiainana maharitra sy fiainana maharitra ary azo itokisana.
4. Ny fiarovana ny angovo sy ny fiarovana ny tontolo iainana : ny valan-javaboary mifehy ny pneumatic
Faritra fampiharana:
Ny fehin-kibo mifehy ny pneumatic dia ampiasaina amin'ny petrochemical, ny herinaratra, ny saha, ny fanafody ary ny fifehezana ny tsiranoka, toy ny fanaraha-maso ny tsiranoka, ny fitsipi-pifehezana, sns. Ny fizotry ny famokarana indostrialy, fanatsarana ny fahombiazan'ny famokarana ary ny fiantohana ny kalitaon'ny vokatra.
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.
