Yintoni iValve yeSango leNtsimbi engaGciniyo
A ivalvu yesango lentsimbi engagqwaliyosisixhobo esibalulekileyo sokulawula ukuhamba kwamanzi esenzelwe ukuqala okanye ukumisa ukuhamba kolwelo, iigesi, okanye ukungcola kwimibhobho yemizi-mveliso. Sisebenza ngokuphakamisa okanye ukwehlisa "isango" eliyingxande okanye elimile okwesinqe ngevili lesandla okanye i-actuator, okuvumela ulawulo oluchanekileyo lokuhamba kolwelo. Eyaziwa ngokuqina kunye nokumelana nokugqwala, iivalvu zesango lentsimbi engagqwaliyo zisetyenziswa kakhulu kumashishini afuna imigangatho ephezulu yococeko, ukumelana neekhemikhali, kunye nokuthembeka phantsi kobushushu obuphezulu okanye uxinzelelo.

Yintoni iStainless Steel
Intsimbi engagqwaliyo yintsimbi esekwe kwi-alloy equlethe ubuncinciI-10.5% ye-chromium, eyenza umaleko we-oxide okhuselayo kumphezulu wayo. Lo maleko uthintela umhlwa kunye nokugqwala, okwenza ukuba ube yindawo efanelekileyo kwiindawo ezinobungozi. Izinto ezongezelelweyo ezifana ne-nickel, i-molybdenum, kunye ne-manganese zonyusa iipropati ezifana namandla, ukuguquguquka, kunye nokumelana ne-oxidation.
