Le valve yebhola enezimbobo ezimbili ezihlanganisiwe ikhiqizwa ngokuhambisana nezindinganiso ze-GB. Umzimba wevalve uphonswe ngokuphelele nge-CF8 (insimbi engagqwali i-304), ihambisana nesihlalo esithambile se-PTFE esisebenza kahle kakhulu ukuze kutholakale ukuvala okuqinile okulingana namabhamuza. Sebenzisa indlela yokushayela ngesandla, ukujikeleza okungu-90° kuphela okungasheshe kuqedele ukuvula nokuvala kwepayipi, ngomzuzu omncane wokusebenza nokusebenza okuguquguqukayo. Isakhiwo sezingxenye ezimbili ezihlukene siletha ukusebenza kalula ekuhlukaniseni nsuku zonke, ekuhlanzeni nasekulungiseni.
