I-OHL yasekwa ngo-1867 kwaye ngoku yenye yabakhiqizi abakhokelayo beevalvu zoshishino eJamani. Zonke iimveliso zenziwe eJamani kwaye ziveliswa ngokungqongqo kunye ne-EU kunye nemigangatho yehlabathi.
Iimveliso zibandakanya iivalvu zebhabhathane eziphindwe kathathu, iivalvu zebhabhathane zesitulo esilastiki, izivalo zebhabhathane ezisembindini njalo njalo. Isetyenziswa ngokubanzi kwishishini lemichiza, amandla elanga, ukwakha iinqanawa, unyango lwamanzi, ishishini lamaphepha njalo njalo.

Yasekwa ngo-1872, i-VAG yinkampani yevalve eseJamani. I-VAG inabasebenzi abali-1,100 kwihlabathi jikelele, ibonelela ngeenkonzo zevalvu ezikhawulezayo neziluncedo kubathengi abavela kwihlabathi liphela.
I-VAG izibophelele ekuboneleleni ngezisombululo zolawulo lwenkqubo yanamhlanje kumadama, izityalo zamanzi, kunye nothungelwano lonikezelo lwamanzi okusela.
Iimveliso ziquka i-Double-offset butterfly valves, i-Centric butterfly valve njalo njalo.

UParker uneminyaka engaphezulu kwe-100 kwaye ebebonelela ngoluhlu olupheleleyo lwezisombululo zonyango lwamanzi kumashishini ehlabathi okanye abathengi bezorhwebo ukunceda abathengi bacombulule imingeni yabo.
UParker ujolise kubathengi kwaye ubonelela ngeendlela ezahlukeneyo zoyilo lweevalvu zebhabhathane ukuhlangabezana neemfuno zabathengi. Ukongeza kwiivalvu zebhabhathane, uParker ukwabonelela ngezixhobo ezahlukeneyo zemizi mveliso onokuthi ukhethe kuzo. UParker ngumthengisi othembekileyo.

IBurgmer yasekwa ngo-1967 kwaye ikomkhulu eJamani, ibandakanyeka kwimveliso yeevalve zebhabhathane. Zonke iivalve ziveliswa ngokuhambelana ne-ISO9001: imigangatho ye-2018. Ukubonelela ngeevalvu zebhabhathane ezikumgangatho ophezulu kubathengi bamashishini. Ukukhonza ishishini lokucoca amanzi, ishishini lokwakha iinqanawa, ishishini le-pulp, ishishini lokuvelisa amandla, njl.

Yasekwa ngo-1966, i-BK Armaturen izibophelele ekuboneleleni abathengi ngeemveliso ezikumgangatho ophezulu kunye neenkonzo zokuhanjiswa ngokukhawuleza. Kwangaxeshanye, i-BK ijolise kwi-application-oriented and customized valves ukubonelela abathengi ngezisombululo zolawulo lwenkqubo ehambelana kakhulu.
Iimveliso ziquka i-eccentric butterfly valves, iivalve zebhabhathane ezigxininisiweyo, iivalve zebhabhathane ezifakwe kwi-PTFE njalo njalo.
