Ivalve yeplagi ethambisayo enomlinganiselo woxinzelelo luhlobo lwevalvu yeshishini eyenzelwe ukulawula ukuhamba kolwelo ngaphakathi kumbhobho.Kulo mxholo, "i-lubricant" ibhekisa kusetyenziso lwesithambiso okanye isitywini ukunciphisa ukukhuhlana nokuqinisekisa ukusebenza kakuhle komatshini wevalvu.Ubukho benkalo yokulinganisa uxinzelelo kuyilo lwevalve yenzelwe ukugcina ulungelelwaniso okanye uxinzelelo olulinganayo kwiindawo ezahlukeneyo zevalve, ezinokunceda ekuphuculeni ukusebenza ngokubanzi kunye nokuthembeka kwevalve, ngakumbi kwizicelo zoxinzelelo oluphezulu. i-lubrication kunye ne-pressure balance kwi-valve yeplagi ijolise ekuphuculeni ukuqina kwayo, ukusebenza kakuhle, kunye nokukwazi ukumelana neemeko zokusebenza ezinzima.Ezi mpawu zinokuba negalelo ekunciphiseni ukuguga kunye nokukrazula, ukuqinisa ukutywinwa kwemfezeko, kunye nokusebenza kakuhle, ekugqibeleni kukhokelela ekusebenzeni okuphuculweyo kunye nobomi obude bevalve kwiindawo zoshishino. ibhalansi yoxinzelelo, zive ukhululekile ukubuza iinkcukacha ezithe vetshe.
1. Uhlobo loxinzelelo loxinzelelo oluguquliweyo lweplagi yeplagi yeplagi yemveliso ye-oyile inengqiqo, ukutywinwa okuthembekileyo, ukusebenza okugqwesileyo, inkangeleko entle;
2. Ivalve yeplagi yesitywina se-oyile inverted pressure balance structure, light switch action;
3. Kukho umjelo we-oyile phakathi komzimba wevalvu kunye nomphezulu wokutywina, onokufaka igrisi yokutywina kwisihlalo sevalvu nangaliphi na ixesha ngombhobho we-oyile ukwandisa ukusebenza kokutywina;
4. Izinto zamacandelo kunye nobukhulu beflange zinokukhethwa ngokufanelekileyo ngokweemeko zokusebenza okanye iimfuno zomsebenzisi ukuhlangabezana neemfuno ezahlukeneyo zobunjineli.

Inkonzo emva kokuthengiswa kwevalve yebhola edadayo ibaluleke kakhulu, kuba kuphela ngexesha elifanelekileyo kunye nenkonzo yokuthengisa emva kokuthengisa inokuqinisekisa ukusebenza kwayo kwexesha elide kunye nokuzinza.Oku kulandelayo yimixholo yenkonzo emva kokuthengiswa kwezinye iivalvu zebhola ezidadayo:
I-1.Ukufakwa kunye nokugunyaziswa: Abasebenzi benkonzo emva kokuthengisa baya kuya kwisayithi ukuze bafake kwaye balungise ivalve yebhola edadayo ukuqinisekisa ukusebenza kwayo okuzinzile kunye nokuqhelekileyo.
I-2.Ukugcinwa: Gcina rhoqo i-valve yebhola edadayo ukuqinisekisa ukuba ikwimeko engcono kakhulu yokusebenza kunye nokunciphisa izinga lokungaphumeleli.
3. Ukulungisa ingxaki: Ukuba ivalve yebhola edadayo ayiphumeleli, abasebenzi benkonzo emva kokuthengisa baya kuqhuba ukujongana neengxaki kwisayithi ngexesha elifutshane ukuqinisekisa ukusebenza kwayo okuqhelekileyo.
I-4.Uhlaziyo lwemveliso kunye nokuphucula: Ukuphendula kwizinto ezintsha kunye nobuchwepheshe obutsha obuvela kwiimarike, abasebenzi benkonzo emva kokuthengisa baya kucebisa ngokukhawuleza ukuhlaziya kunye nokuphucula izisombululo kubathengi ukuba babonelele ngeemveliso ezingcono ze-valve.
5. Uqeqesho lolwazi: Abasebenzi benkonzo yasemva kokuthengisa baya kubonelela ngolwazi lwevalvu kubasebenzisi ukuphucula inqanaba lolawulo nololongo lwabasebenzisi abasebenzisa iivalvu zebhola ezidadayo.Ngamafutshane, inkonzo emva kokuthengiswa kwevalve yebhola edadayo kufuneka iqinisekiswe macala onke.Kuphela ngale ndlela inokuzisa abasebenzisi amava angcono kunye nokhuseleko lokuthenga.
