(1) Iivalvu zokwakha ezidolophini: iivalvu ezinoxinzelelo oluphantsi zihlala zisetyenziswa kwiinkqubo zokwakha ezidolophini, kwaye okwangoku ziphuhliswa ngendlela yokukhusela okusingqongileyo kunye nokonga umbane.
Iivalvu zerabha ezinobuhlobo nokusingqongileyo, iivalvu zokulinganisela, iivalvu zebhabhathane eziphakathi, kunye neevalvu zebhabhathane ezitywiniweyo ngesinyithi ziya zithatha indawo yeevalvu zesango lesinyithi ezinoxinzelelo oluphantsi. Uninzi lweevalvu ezisetyenziswa kwizakhiwo zasezidolophini zasekhaya ziivalvu zokulinganisela, iivalvu zesango ezitywiniweyo, iivalvu zebhabhathane, njl.njl.
(2) Iivalvu zokufudumeza ezidolophini: kufuneka inani elikhulu leevalvu zebhabhathane ezitywiniweyo ngesinyithi, iivalvu zebhalansi ethe tye kunye neevalvu zebhola ezingcwatywe ngqo kwinkqubo yokufudumeza ezidolophini. Ezi valve zisombulula ingxaki yokungalingani kwe-hydraulic ethe nkqo nethe tyaba yombhobho, zifezekisa ukonga amandla, kwaye zinciphise ukuvelisa ubushushu. Injongo.
(3) Iivalvu zegesi yesixeko: Igesi yesixeko ibandakanya i-22% yemarike yegesi yendalo yonke, kwaye inani leevalvu likhulu kwaye kukho iintlobo ezininzi. Ngokuyintloko kufuneka ivalvu yebhola, ivalvu yeplagi, ivalvu yokunciphisa uxinzelelo, ivalvu yokhuseleko.
(4) Iivalvu zemibhobho emide: iipayipi ezikude ikakhulu yioyile ekrwada, iimveliso ezigqityiweyo kunye nemibhobho yendalo. Iivalvu ezifunwa luninzi lwale mibhobho ziivalvu zebhola ezigcweleyo zentsimbi eziziinxalenye ezintathu, iivalvu zesango elisicaba elichasene nesulfur, iivalvu zokhuseleko, kunye neevalvu zokujonga.
(5) Iivalvu zokukhusela okusingqongileyo: Inkqubo yokubonelela ngamanzi kwinkqubo yokukhusela okusingqongileyo yasekhaya kufuneka isebenzise ivalvu yebhabhathane ephakathi, ivalvu yesango etywiniweyo, ivalvu yebhola, kunye nevalvu yokukhupha umoya (eyomileyo ukuze kususwe umoya okwipayipi, kwaye inkqubo yokucoca amanzi amdaka kufuneka isebenzise ivalvu yebhabhathane etywiniweyo kunye nevalvu yebhabhathane.
