Ny lakolosy pneumatic dia mifehy ny valve dia valve mifehy ny valve izay mampiasa fitaovana pneumatic mba hifehezana ny tsiranoka tsiranoka.
Toy izao manaraka izao ny endriny lehibe:
1. Ny firafitry ny faneva : bolosa-bolo pneumatic dia mampiasa lakolosy ho toy ny singa mifehy ny singa, izay manana fampisehoana tsara sy elastika tsara ary afaka mampifanaraka ny toe-piainana henjana toy ny mari-pana sy ny fanerena avo sy ny fanerena avo lenta, ny fanerena avo sy ny fanerena avo sy ny fanerena avo lenta, ny tsindry avo sy ny fanerena avo lenta, ny fanerena avo sy ny fanerena avo lenta, ny fanerena avo sy ny fanerena avo sy ny fanerena avo lenta, ny fanerena mafy sy ny fanerena avo lenta, ny fanerena avo sy ny fanerena avo sy ny fanerena avo lenta.
2. Fanitsiana tsara : Ny fanodikodinam-bolo mifehy ny valve dia mifehy ny fanitarana sy ny fanakatonana ny lakolosy amin'ny alàlan'ny fitaovana voadona, ka hahatratra ny fanitsiana ny tsiranoka, ary ny fahitsiana sy ny fitoniana avo lenta.
3. Valiny haingana : Ny fanalahidin'ny fanodikodinam-bolo dia mifehy ny valve dia manana fotoana fanarenana lava be dia be ary afaka mamaly haingana ny famantarana ny fifehezana mba hahatratrarana fanitsiana haingana.
Raha tsorina, ny valizy mifehy ny bela-boninkazo dia manana ny toetoetran'ny fanitsiana tsara, ny valiny haingana, tsy misy leakage, fanoherana ny fanoherana ary fahatokisana avo sy fahatokisana avo. Izy ireo dia ampiasaina amin'ny rafitra fanaraha-maso tsiranoka ao amin'ny petroleum, indostria simika, metallurgy, hery herinaratra ary indostria hafa.
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.
