Bupati buli kabotu bwa ANSI-Standard check valves

Chivvalavu yakulangazyakabambwa, zyakabambwa, zyakabambwa akusunkwa kweendelana azyeelelo zyaku Amelika zyiitwa kuti zyeelelo zyaku Amelikavvalavu yakulanga, aboobo ino bupati buli buti bwachiimo chaku Amelikavvalavu yakulanga? Ino nkwiindana kuli buti aakati kachintu eecho achibelesyo chakulanga chiimo chenyika yoonse? Kwalino, bupati buli kabotu bwaku Amelikamavalvu aakulanganchintu chidumide loko kuti chakapangwa akupangwa kweendelana azyeelelo zya API antoomwe a ASME, mpawo zyeelelo zyiingi zyaku Amelika zilidumide munyika yoonse.
