Ivalvu iyingxenye eyisisekelo yohlelo lwamapayipi futhi ithatha isikhundla esibaluleke kakhulu embonini yemishini.Inohlu olubanzi lwezinhlelo zokusebenza.Kuyingxenye edingekayo kunjiniyela wokudlulisa uketshezi, uketshezi kanye negesi.Kuphinde kube yingxenye ebalulekile yemishini embonini yamandla enuzi, embonini ye-petrochemical, ukuhlinzekwa kwamanzi nokushisisa, kanye nezinkundla zomphakathi.Idatha yemboni ye-valve yomhlaba wonke eminyakeni emithathu edlule, ukuphuma kwama-valve emhlabeni wonke bekungamasethi ayizigidi eziyizinkulungwane eziyi-19.5-20, futhi inani lokukhiphayo landa kancane kancane.Ngo-2019, inani eliphumayo lama-valve emhlabeni wonke lalingama-US $64 billion, ngo-2020, inani eliphumayo lama-valve emhlabeni wonke lalingama-US $73.2 billion, kwathi ngo-2021, inani eliphumayo lamavalvu womhlaba lalingama-US $76 billion.Eminyakeni emibili yakamuva, ngenxa yokwehla kwamandla emali emhlabeni wonke, inani lokukhipha i-valve liye landa kakhulu.Ngemva kokudonsa ukwehla kwamandla emali, inani eliphumayo levalvu yomhlaba wonke liye lahlala cishe ku-3%.Kulinganiselwa ukuthi ngo-2025, inani lokukhipha ama-valve emhlabeni wonke lizofinyelela cishe ku-US $ 90 billion.
Embonini ye-valve yomhlaba wonke, e-United States, eJalimane, eJapane, eFrance naseTaiwan, i-China ingeye-echelon yokuqala yamandla aphelele, futhi ama-valve awo athatha imakethe ephezulu yemboni.
Kusukela ngeminyaka yawo-1980, i-United States, Japan, Germany, South Korea kanye namanye amazwe kancane kancane adlulisela izimboni ezisezingeni eliphakathi nezisezingeni eliphansi emazweni asathuthuka.I-China iyizwe elinemboni yamavalvu egxile kakhulu futhi ekhula ngokushesha kakhulu.
Njengamanje, isiyizwe elikhulu kunawo wonke embonini yama-valve emhlabeni mayelana nokukhiqizwa nokuthekelisa kwama-valve, futhi isivele ibheke ezweni lama-valve anamandla.
