I-valve yepneumatic yebhola enentambo ivela ku-globe valve. Yabelana ngesenzo esifanayo sokujikeleza esingu-90 degrees, kodwa umehluko usesikhunjeni sayo, esiyindilinga futhi sinenkalo eqondile noma imbobo eduze nomgogodla wayo. Isilinganiso sobubanzi besikhumba esiyindilinga esivulekayo embobeni siklanyelwe ukuthi lapho ibhola lijikeleza ngo-90 degrees, isikhumba esiyindilinga sibonakala ngokuphelele ekungeneni nasekuphumeni, ngaleyo ndlela sivimbe ukugeleza.

I-threaded pneumatic ball valve idinga kuphela ukujikeleza okungu-90-degree kanye ne-torque encane ukuze kufezeke uphawu oluqinile. Isikhala sangaphakathi esilinganayo ngokuphelele somzimba we-valve sihlinzeka ngendlela yokugeleza enokuphikiswa okuphansi, eqondile yomidiya. Ngenkathi i-ball valves ngokuvamile ithathwa njengokufanele kakhulu ekusebenzeni okulula okuvulekayo/okuvalwayo, intuthuko yakamuva ivumele ukwakheka okuvumela i-ball valves ukuthi yenze imisebenzi yokudonsa nokulawula ukugeleza.
