348 Series

Heavy-duty ball valve in brass for boiler discharge, with blowout-proof stem.

Applications

The valve mod. 348 is used in heating systems. The rubber ring avoids the use of sealing materials on the thread (PTFE, paste, etc.) as a result allowing easy installation as well as tight sealing when adjusting the valve position. The butterfly handle with lock makes it possible to fasten the valve securely in position (open or closed). The DN12 oversize bore enhances the discharge speed.
