Rubinetti
Con una valvola a sfera, i rubinetti di arresto controllano il flusso di liquidi e gas a bassa pressione nei sistemi di distribuzione. Inseriti nelle corrispondenti parti femminili, i tappi sono disponibili in varie configurazioni di fori. Spesso dotati di estremità coniche, consentono di accogliere una gamma più ampia di diametri di tubi per aumentare la flessibilità operativa. I rubinetti di arresto di alta qualità, a tenuta stagna, sono adatti ad applicazioni sotto vuoto e sono disponibili in vetro smerigliato o in plastica, eliminando la necessità di lubrificazione.
