Kuva aho amazi aturuka kugeza aho abikwa, kuva aho atunganyirizwa kugeza aho akwirakwizwa, Amabwiriza ya AWWA akubiyemo ibicuruzwa n’imikorere bifitanye isano n’ibice byose byo gutunganya no gutanga amazi. AWWA C504 ni imwe mu mabwiriza asanzwe, ni ubwoko bw’agasanduku k’ibinyugunyugu gakoreshwa mu kwicara mu birunga.
Valve y'ikinyugunyugu ya AWWA C504 ifite imiterere ibiri, agafunga k'umurongo wo hagati n'agafunga k'umurongo wo hagati, ubusanzwe, igiciro cya agafunga k'umurongo wo hagati kizaba gihendutse ugereranije n'agafunga k'umurongo wo hagati, birumvikana ko ibi bikorwa muri rusange hakurikijwe ibyo abakiriya bakeneye. Ubusanzwe igitutu cy'imikorere ya AWWA C504 ni 125psi, 150psi, 250psi, igipimo cy'umuvuduko w'ihuza ry'urukiramende ni CL125, CL150, CL250.
Valve y'ibinyugunyugu ya AWWA C504 ikoreshwa cyane cyane mu mishinga yo gutunganya amazi, igikoresho gikenewe ni amazi adafite umwanda, imiterere y'agapfunyika k'umukara yongera ubushobozi bwo gufunga valve, kugira ngo valve ibashe gusohora 0. Mu guhitamo ibikoresho by'umubiri wa valve, ubusanzwe icyuma gifunga ni cyo gikurura, hagakurikiraho icyuma cya karuboni. Guhitamo impeta yo gufunga disc ya valve, EPDM, NBR, NR birahari, hakurikijwe ibyo umukiriya akeneye kugira ngo ahitemo.
Ugereranyije na valves za EN558-13,14 series butterfly, valve ya AWWA C504 butterfly ifite umubiri munini n'umurambararo munini, kandi hari itandukaniro rito mu bindi bipimo, nk'uko bigaragara mu mbonerahamwe ikurikira. Birumvikana ko ku bijyanye n'imikorere, nta tandukaniro rinini rihari ku zindi valves za butterfly zifunze neza.
