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 DN50 and 2 O-ring seals DN65 and bigger, 3O-ring for DN350 and bigger.
