3-Way Changeover Ball Valve DBF-D
Technical Description
The ball valves type DBF-C and DBF-D consist of a 3-piece body. The stem is blow-out proof and from nominal size DN 32 onwards is equipped with a double O-ring seal. When using these ball valves, it must be noted that they are changeover ball valves with regard to sealing. The pressure inlet must therefore be in the center. Actuators can be mounted using a mounting kit. This retrofitting capability must be specified when ordering (additional charge).
