I-valve yokuhlola isisekelo sepulasitiki yethusi iwuhlobo oluvamile lwe-valve ehlanganisa into yethusi kanye nomgogodla wepulasitiki. Isetshenziselwa kakhulu ukulawula ukugeleza koketshezi noma igesi epayipini nokuvimbela ukugeleza emuva noma ukuhlehla.
I-Brass iyimpahla yekhwalithi ephezulu ekwazi ukumelana nokugqwala okuhle namandla, engagcina ukusebenza okuzinzile ngaphansi kwezimo ezihlukene zokusebenza. I-valve core yepulasitiki yenziwe ngamapulasitiki wobunjiniyela bezinga eliphezulu, anokuvalwa okuhle nokungagqwali, futhi ingaqinisekisa ukuvala nokuqina kwevalvu.
I-valve yokuhlola inesakhiwo esilula, ukufakwa kalula nokugcinwa, isikhathi sokulondoloza kanye nezindleko zomsebenzi.
Ama-valve epulasitiki ethusi asetshenziswa kakhulu embonini, ekwakhiweni, ekuphakeleni kwamanzi emphakathini nasezinhlelweni zokudonsa amanzi, njll., futhi angasetshenziswa ukuvimbela ukugeleza kwamanzi, ukugeleza kwegesi emuva, njll., kanye nokuqinisekisa ukusebenza okuvamile kwesistimu yamapayipi.
