Qinisekisa ukuthi i-valve ivaleke ngokuphelele kuzo zombili izinhlangothi; ukuqedwa komzimba we-valve ne-valve plate, i-torque encane, impilo ende yesevisi; ama-bearing amathathu ku-stem avimbela i-stem ukuthi ingagobi futhi aqinisekise ukusetshenziswa okuhle kakhulu; Ingafakwa kunoma yisiphi isikhundla; Umzimba we-valve awudingi isondlo, ungasuswa, izinto ezingasetshenziswa kabusha. Imikhiqizo isetshenziswa embonini yamachemikhali ne-petrochemical, ubuchwepheshe bokwelapha amanzi nodoti, ubuchwepheshe bokwelapha igesi, ukwakhiwa kwemikhumbi, ubunjiniyela bamandla, imboni yokudla, ubunjiniyela bakamasipala, ukwelashwa kwendawo engena-silicon, imboni entsha yamabhethri e-lithium. Ihlangabezana ne-GB/T 122382008/EN 593 standard. Izinto ezihlukene zingakhethwa ngokuya ngesimo sokusetshenziswa kwezimboni ezahlukene.
