Ny valva fanaraha-maso ny pneumatic dia manana ny toetran'ny fanitsiana voafaritra, ny valiny haingana, ny fanoherana ny fanimbana, ny tombo-kase tsara, ny firafitra, tsotra ary azo itokisana, ary fiainana maharitra, ary fiainana maharitra ary fiainana maharitra. Izy ireo dia ampiasaina be amin'ny fifehezana sy ny fitsipi-pitondran-tena amin'ny sehatra indostrialy isan-karazany.
Toetoetra:
1. Ny tombo-kase tsara : ny valve fanaraha-maso ny pneumatic sofa dia manana fampisehoana fanimbana tsara, izay afaka manakana ny tsiranoka amin'ny tsiranoka ary hiantoka ny fampandehanana azo antoka ny rafitra.
2. Ny rafitra tsotra sy azo itokisana : ny fantsom-pifehezana salohim-bary dia manana rafitra tsotra, mora kokoa ny mitazona sy mametraka ary azo itokisana sy fitoniana avo lenta.
3. Fiainana serivisy lava : Ny seza misy valve sy ny valve dia vita amin'ny fitaovana mitambatra, izay manana fiainana maharitra ary afaka mahafeno ny filàna asa maharitra maharitra ela.
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.
