Ivalve yokhuseleko sisixhobo sokhuseleko esizenzekelayo esinokukhulula ngokukhawuleza umphunga xa uxinzelelo luphezulu kakhulu ukuthintela iingozi zokudubula. Ingumgca wokugqibela wokukhusela kwiingozi zejenereyitha yomphunga kwaye ikwayinto ephambili yesixhobo sokuqinisekisa ukhuseleko lobomi kunye nokuthembeka kwezixhobo. Ngokuqhelekileyo, i-generator yomphunga kufuneka ifakwe kunye neevalvu ezimbini zokhuseleko. Ngokuqhelekileyo, ukufuduka okulinganiselwe kwevalve yokhuseleko kufuneka kube ngaphantsi komthamo omkhulu wokucubungula we-generator ye-steam ukuqinisekisa ukusebenza okuqhelekileyo kumthwalo ophezulu.
Ukugcinwa nokugcinwa kweevalvu zokhuseleko nako kubaluleke kakhulu. Ngethuba lokusetyenziswa, ukuchaneka kunye nokuvakalelwa kwe-valve yokukhusela kufuneka kuhlolwe rhoqo, kwaye ukugcinwa kufuneka kuqhutywe ngokuhambelana nemiyalelo yokusetyenziswa kunye nokugcinwa kwencwadana. Ukuba iimpawu zokungaphumeleli okanye ukungasebenzi zifunyenwe kwi-valve yokukhusela, kufuneka ithathelwe indawo okanye ilungiswe ngexesha ukuze kuqinisekiswe ukusebenza okukhuselekileyo kwejeneretha ye-steam.
Ke ngoko, ivalve yokhuseleko kwijenereyitha yomphunga sisixhobo esiyimfuneko. Akuyena kuphela umgca wokugqibela wokukhusela ukuqinisekisa ukhuseleko lwabasebenzi, kodwa kunye nomlinganiselo obalulekileyo wokukhusela ingqibelelo kunye nokuzinza kokusebenza kwezixhobo. Ukuze kuqinisekiswe ukusebenza ngokukhuselekileyo kwejeneretha ye-steam, kufuneka sinikele ingqalelo kwiinkalo ezininzi ezifana nokukhethwa, ukufakwa, ukugcinwa kunye nokugcinwa kwe-valve yokukhusela.
