Pneamic Spive Valve ndi valavu yomwe imagwiritsa ntchito mphamvu ya chibayo yoyendetsa madzi ndikukakamizidwa. Imakhala ndi thupi la valavu, malaya, valavu, piston, masika
ndi chibayo. Valavu iyi imasintha malo a valavu yolumikizira ndikusintha njira ya madzi kudzera mu valavu kudutsa mu valavu, potero kusintha kutuluka ndi kukakamizidwa.
Pneumatic Stoeve Remouting Valve ili ndi izi:
1. Kuwongolera kolondola : Kapangidwe ka Valavu ndi malaya kumathandizira valavu molondola ndikuwongolera madzi akumadzi kuti akwaniritse zofunika zosiyanasiyana.
2. Kuyankha mwachangu : Chifukwa cha kugwiritsa ntchito kwa ochita za ma nerumotic, valavu yowonera bwino kwambiri
kutuluka ndi kukakamiza kwa madzimadzi.
3. Kudalirika kwakukulu : valavu imapangidwa ndi zinthu zapamwamba kwambiri, ndikukana zabwino zokoka komanso kuvala molimba, ndipo imatha kugwira ntchito mokhazikika kwa nthawi yayitali pakugwira ntchito mwankhanza.
4. Kukonza mosavuta : valavu imakhala ndi kapangidwe kambiri ndipo ndikosavuta kusokoneza ndikukonza, zomwe zingachepetse nthawi yokonza ndi ndalama.
5. Kugwiritsa ntchito mavalidwe oyendetsa bwino kwambiri : Makulidwe oyendetsera ma pnruutic oyenera ndioyenera mafakitale osiyanasiyana, monga makampani ogulitsa mankhwala, mafuta, mphamvu yamagetsi, metaldurgy, etc.,
Ndipo itha kugwiritsidwa ntchito kuwongolera kuyenda ndikukakamizidwa zakumwa, mpweya ndi nthunzi.
Zogulitsa zazikuluzikulu zimaphatikizapo valavu yowongolera ya chibayo, valavu ya mpira, valavu yamagetsi, valavu yopendekera, yopatsa chidwi.
