Valavu ya API chitsulo cha flange padziko lonse lapansi:

Kuyika kwa APIMa valve a globe a flange achitsulo amapangidwa ndi diski ya plug yosunthika yokhala ndi chitseko chathyathyathya kapena chozungulira kuti chitseke. Kawirikawiri, pulagi imalumikizidwa ku tsinde lomwe limagwiritsidwa ntchito ndi screw action ngati mzere wowongoka pogwiritsa ntchito mawilo amanja. Kawirikawiri, ma valve a globe awa amangogwiritsidwa ntchito potsegula ndi kutseka kwathunthu, osati poletsa kayendedwe ka madzi. Kupanikizika kumachokera ku Class 150 mpaka Class 600 ndipo kutentha kwa ntchito ndi kuyambira -29 mpaka 450digiri. Ma valve achitsulo awa amagwiritsidwa ntchito kwambiri pamafuta, mankhwala, mankhwala, mankhwala ndi ufa wa mapaipi kuti azitha kusuntha zinthu. Pali mawilo amanja, zida za bevel, magetsi ndi ma actuator oyendetsedwa ndi pneumatic.
