Umehluko phakathi kwevalve yesango le-OS&Y kanye nevalvu yesango le-NRS

1.Isiqu sei-valve yesango ye-OS&Yivezwa, kuyilapho isiqu sei-NRSi-valve yesangousei-valveumzimba.

2.I-OS&Yi-valve yesango iqhutshwa ukudluliswa kwentambo phakathi kwesiqu se-valve kanye nesondo lokuqondisa, ngaleyo ndlela ishayela isango ukuthi likhuphuke futhi liwe. II-NRSi-valve yesango ishayela isango ukuthi likhuphuke futhi liwele ngokujikeleza kwesiqu se-valve endaweni engashintshi. Lapho ushintsha, isondo lokuqondisa kanye nesiqu se-valve kuxhunywa ndawonye futhi kume kancane

3.Intambo yokudlulisa ye-NRSi-valve yesango itholakala ngaphakathi komzimba we-valve. Phakathi nenqubo yokuvula nokuvala i-valve, isiqu se-valve sijikeleza kuphela endaweni, futhi isimo sokuvula nokuvala se-valve asinakuhlulelwa ngeso lenyama. Intambo yedrayivu esiqwini seOS&Yi-valve yesango ivezwa ngaphandle komzimba we-valve, futhi ukuvulwa nokuvala kanye nesimo sesango kungahlulelwa ngokunembile.

4. Ubude bobude be-NRSi-valve yesango incane, futhi indawo yokufaka incane. IOS&Yi-valve yesango inokuphakama okukhulu uma ivuliwe ngokugcwele, futhi idinga indawo enkulu yokufaka.

5. Isiqu se-OS&Yi-valve yesango ingaphandle komzimba we-valve, elungele ukulungiswa nokugcotshwa. I-stem thread yeI-NRSi-valve yesango ingaphakathi komzimba we-valve, okunzima ukuyigcina nokugcoba, futhi isiqu se-valve siguguleka kalula yi-medium, futhi i-valve yonakaliswa kalula. Emkhakheni wokusetshenziswa, i-OS&Yi-valve yesango ibanzi kakhulu.
