I-valve yepneumatiki enentambo ibuye ivela ku-globe valve. Yabelana ngesenzo esifanayo sokujikeleza esingu-90 degrees, kodwa umehluko usesemzimbeni wayo we-plug, ongokwe-spherical futhi unomgodi ovulekile noma imbobo ehamba ngaphakathi kwi-axis yayo. Isilinganiso se-spherical surface kumbobo yesiteshi siklanyelwe ukuze lapho ibhola lijikeleza ngo-90 degrees, i-spherical surface ivezwe ngokuphelele ekungeneni nasekuphumeni, ngaleyo ndlela ivala ukuhamba.

I-threaded pneumatic ball valve idinga kuphela ukujikeleza okungu-90-degree kanye ne-torque encane ukuze kufezeke uphawu oluqinile. Indawo engaphakathi elingana ngokuphelele yomzimba we-valve ihlinzeka ngendlela yokugeleza enokuphikiswa okuphansi, eqondile yomidiya. Ngenkathi ama-ball valve ngokuvamile athathwa njengafanele kakhulu ukusebenza okulula okuvula/ukuvala, intuthuko yakamuva ivumele imiklamo evumela ama-ball valve ukuthi enze imisebenzi yokudonsa nokulawula ukugeleza.
