Ukuvala i-valve yamanzi kusetshenziselwa ikakhulukazi ukukhiya i-valve yamanzi nokuvikela ukuphepha kwe-valve.Ukuthi idivayisi yokuvala ivalvu yamanzi iyasetshenziswa noma cha kuhlobene nokubaluleka kokusebenza okuphephile;Amanye ama-valve avame ukuvuleka, amanye ama-valve avame ukuvalwa, okudinga ukucatshangelwa kokuphepha, ukuze ugweme ukungasebenzi kahle, ngakho-ke umklamo wokuvala i-valve yamanzi, inhloso ukuqinisekisa ukuthi ukusetshenziswa kwemishini ye-valve ivaliwe ngokuphelele, imishini. igcinwa isesimweni esiphephile;Ukuvalwa kwevalvu yamanzi kungavimbela ukusetshenziswa kwedivayisi ngephutha, okuholela ekulimaleni noma ekufeni, kodwa futhi kungaba yisixwayiso.

Uhlelo lokusebenza lwedivayisi yokuvala i-valve yamanzi

• 1. Ama-valve amapayipi asetshenziswa ezinhlelweni zamapayipi e-petroleum, amakhemikhali nezimboni;
• 2. Amavalvu amapayipi okonga amanzi, amandla kagesi, kamasipala nezinye izinhlelo zamapayipi kahulumeni;
• 3. Ama-valve amapayipi afaneleka ezinhlelweni zamapayipi amakhulu njengekhemisi, ukwenza amaphepha, insimbi nesiphuzo;
• 4. I-valve yamapayipi efanelekile ohlelweni lwamapayipi embonini yezokwakha, isifunda sezohwebo, indawo yokuhlala yomndeni, njll.;
• 5. Isebenza kuzo zonke ezinye izinhlelo zamapayipi ezinamavalvu ukuze zivikeleke.
