Ma valve owunika, ma valve osabwerera, adapangidwa kuti aletse kusinthika kwa kayendedwe ka mapaipi.Ma valve awa amayendetsedwa ndi zinthu zomwe zikuyenda mu payipi.Kuthamanga kwa madzi omwe akudutsa mu dongosolo kumatsegula valavu, pamene kutembenuka kulikonse kudzatseka valve.Kutseka kumatheka ndi kulemera kwa makina a chekeni, ndi kupanikizika kwa msana, ndi kasupe, kapena mwa kuphatikiza njirazi.

valavu yoyendera bonnet yosindikizidwa, valavu yopindika yopangidwa ndikupangidwa molingana ndi ASME B16.34, kuyesa ndikuwona API598, API6D.

Kutsegula kumeneko kuyenera kumveka bwino kuti chilichonse chidutse.Chimbalecho chimamangiriridwa ku hinge, kotero chimbale chimatha kutseguka kapena kutsekedwa pamene madzi agunda disk.Zili ngati khomo lozungulira.Njira yoyendetsera ndi yofunika kwambiri mukamagwiritsa ntchito ma valve awa.

Monga tanena kale, valavu yoyang'ana swing ndi ya nthawi yomwe mukufuna madzi akuyenda mbali imodzi yokha.Chinthu chinanso chofunikira chokhudza ma valve awa ndi chakuti safuna mphamvu zakunja, zomwe zimawapangitsa kukhala abwino kwa ntchito zosiyanasiyana.Amalolanso madzimadzi kudutsa popanda kuchedwetsa kutuluka kwambiri atatsegula kwathunthu.Ma valve a swing check nthawi zambiri amaikidwa pamodzi ndi ma valve a zipata chifukwa amapereka kuyenda kwaulere.Amayamikiridwa pamizere yokhala ndi liwiro lotsika ndipo sayenera kugwiritsidwa ntchito pamizere yokhala ndi kugunda kwamphamvu pamene kuwomba mosalekeza kapena kugunda kungawononge malo okhala.Mkhalidwewu ukhoza kukonzedwa pang'ono pogwiritsa ntchito lever yakunja ndi kulemera kwake.
