Detail Information

Fullly Welded Heating ball valve
 
The complete valve body and weld ends are welded together. There are no potentially leaking flanged or bolted connections on the valve body. The blowout-proof stem is externally sealed with two O-ring seals and a graphite reinforced PTFE washer pressed on by the media pressure. System safety is ensured by the possibility of replacing the upper O-ring seal up to DN 50 and 2 O-ring seals DN65 and bigger, 3 O-ring for DN350 and bigger.
