Olowa mkati amati zaka zingapo zikubwerazi zidzakhala zodabwitsa kwambiri pamakampani opanga ma valve.Kugwedeza kudzakulitsa mayendedwe a polarization mu mtundu wa ma valve.Zikuyembekezeredwa kuti m'zaka zingapo zikubwerazi, padzakhala opanga ma valve ochepa omwe alipo.Komabe, kugwedezeka kudzabweretsa mwayi wambiri.Kugwedezeka kumapangitsa kuti msika ugwire ntchito bwino.
Misika yapadziko lonse lapansi imayang'ana kwambiri mayiko kapena madera omwe ali ndi chuma chotukuka kwambiri kapena mafakitale.Malingana ndi deta kuchokera ku McIlvaine ogula ma valve 10 ofunika kwambiri padziko lapansi anali China, US, Japan, Russia, India, Germany, Brazil, Saudi Arabia, Korea ndi UK.Pakati pawo, msika ku China, US ndi Japan womwe unali pamwamba pa atatu unali 8.847 biliyoni USD, 8.815 biliyoni USD ndi 2.668 biliyoni USD motsatana.Pankhani yamisika yachigawo, East Asia, North America ndi West Europe ndiye msika waukulu kwambiri wama valve padziko lonse lapansi.Zaka zaposachedwa, zofuna za mavavu m'mayiko omwe akutukuka kumene (China monga nthumwi) ndi Middle East zimakula kwambiri, zikuyamba kuchitika ku EU ndi North America kuti zikhale injini yatsopano ya kukula kwa makampani a valavu padziko lonse lapansi.
Pofika chaka cha 2015, kukula kwa msika wa ma valve a mafakitale ku Brazil, Russia, India ndi China (BRIC) kudzafika ku 1.789 biliyoni USD, 2.767 biliyoni USD, 2.860 biliyoni USD ndi 10.938 biliyoni USD, 18.354 biliyoni USD yonse, kuwonjezeka ndi 23.25% poyerekeza ndi 2012. Kukula kwa msika wonse kudzawerengera 30.45% ya kukula kwa msika wapadziko lonse.Monga ogulitsa mafuta achikhalidwe, Middle East ikukulanso mpaka kumafakitale otsika amafuta ndi gasi kudzera pamapulogalamu oyenga mafuta opangidwa atsopano omwe amayendetsa kuchuluka kwazinthu zama valve.
Chifukwa chachikulu chomwe msika wa ma valve m'maiko omwe akutukuka kumene ukukulirakulira ndikuti kukula kwakukulu kwachuma m'maiko amenewo kumayendetsa mafuta ndi gasi, mphamvu, mafakitale amafuta ndi mafakitale ena akumunsi a ma valve kuti atukuke, kumapangitsa kuti ma valve apite patsogolo.
