1. Isingeniso esifushane
Indlela yokunyakaza kwevalvu iqonde ngqo ohlangothini loketshezi, isango lisetshenziselwa ukusika i-medium. Uma kudinga ukuqina okuphezulu, indandatho yokuvala yohlobo lwe-O ingasetshenziswa ukuthola ukuvala okuqondile.
I-valve yesango lommese inesikhala esincane sokufakwa, akulula ukuqoqa udoti nokunye.
I-valve yesango lommese ngokuvamile kufanele ifakwe ngokuqondile epayipini.
2. Isicelo
Leli valuvu lesango lommese lisetshenziswa kabanzi embonini yamakhemikhali, amalahle, ushukela, indle, ukwenza amaphepha kanye neminye imikhakha. Liyivaluvu evalwe kahle, efaneleka kakhulu ukulungisa nokusika ipayipi embonini yamaphepha.
3. Izici
(a) Isango elivulekela phezulu lingakhuhla izinamathiseli eziphezu kokuvala bese lisusa ngokuzenzakalelayo imfucuza.
(b) Isakhiwo esifushane singonga izinto zokwakha kanye nendawo yokufaka, futhi sisekele ngempumelelo amandla epayipi.
(c) Umklamo wokupakisha uphawu lwesayensi wenza uphawu olungaphezulu luphephe futhi lusebenze kahle futhi luqine
(d) Umklamo wokuqinisa umzimba we-valve uthuthukisa amandla onke
(e) Ukuvalwa kwezinhlangothi ezimbili
(f) Iziphetho zeflange zingaba yiziphetho zeflange ze-PN16, futhi ingcindezi yokusebenza ingaba phezulu kunevalvu yesango lommese evamile.
4. Ukuboniswa komkhiqizo
