Iimpawu zevalvu yesango lemela kunye nemeko yokusebenza, kunye nezilumkiso zokuthengwa kwempahla, kunye nokugcinwa kwentshayelelo eneenkcukacha ivelufa yesango lemela sisivalo esikumbhobho esinomsebenzi wokuvala, ukulawula nokulawula ulwelo. Iimpawu zayo eziphambili kukutywinwa kakuhle, isakhiwo esilula, kulula ukuvula nokuvala. Ivalve yesango lemela ifanelekile kumanzi acocekileyo, ugutyulo, amanzi olwandle, igesi, i-oyile, umphunga kunye neminye imithombo yeendaba, ehlala isetyenziswa kushishino lweekhemikhali, ukucocwa kwamanzi, umasipala, unikezelo lwamanzi, ishishini jikelele kunye nezinye iindawo. Xa kuthengwa i-valve yesango le-knife, la manqaku alandelayo kufuneka ahlawulelwe ingqalelo: 1. Ukumisela i-medium yokusebenza kunye noxinzelelo lokusebenza, khetha izinto ezifanelekileyo kunye neenkcukacha; 2. Qinisekisa indlela yokudibanisa kunye nobude besakhiwo sevalve ukuqinisekisa ukuba ihambelana nombhobho; 3. Ngaphambi kokuthenga, kuyimfuneko ukujonga umenzi kunye nesiqinisekiso somgangatho wesiqinisekiso somgangatho wemveliso ukuqinisekisa umgangatho othembekileyo wemveliso; Ukulungiswa kunye nokugcinwa kwevalve yesango lemela kubandakanya le miba ilandelayo: 1. Qwalasela ukusebenza kokutywinwa kwevalvu rhoqo, buyisela iindawo zokutywina kwaye ulungise ukunxitywa komphezulu ngexesha xa iingxaki zifunyenwe; 2. Jonga rhoqo ukuguquguquka, ukuchaneka kunye nokuqina kwendlela yokuhambisa i-valve kunye nomatshini wokusebenza, kwaye utshintshe iindawo ngexesha xa iingxaki zifunyenwe; 3. Jonga rhoqo ukubola kunye nokonakala kwendawo yezinto zevalve, ukucocwa kwangexesha, ukugcinwa nokutshintshwa; 4. Lubricate kwaye ugcine ivalve rhoqo ukuqinisekisa ukuguquguquka kwayo kunye nobomi benkonzo. Ngamafutshane, i-valve yesango lomese luhlobo oluqhelekileyo lwe-valve, ekusetyenzisweni, ukuthengwa kunye nokugcinwa kwezinto kufuneka kuhlawule ingqwalasela engakumbi ukuqinisekisa ukusebenza kwayo okuqhelekileyo, okuzinzileyo nokuthembekileyo.
