Imiba ephambili yoKhetho lweValve kunye neNkqubo yokuBopha
| Ukuqwalaselwa komsebenzi kunye nenkonzo |
|
| Ukukhetha |
| Iivalvu zisebenza ngenjongo yokulawula i-fuids kwiinkonzo zemibhobho yokwakha. |
| Ukhetho olufanelekileyo lubalulekile ukuze kuqinisekiswe ezona nkqubo zisebenzayo, zineendleko kunye nezihlala ixesha elide. |
|
| Umsebenzi |
