Abstract

A valve arrangement which is especially designed for district heatign systems and can be laid in the ground comprises a valve (1) which it should be possible to open and close by rotary movements. The bonnet (11) of the valve body and the valve stem (8) have connections (13, 15-17) which are located above the insulation (18), as is the stuffing box (14). The valve is combined with a bonnet extension (20) and a stem extension (21) which can be attached via the connections and which form a pressure-free upper part. The valve is thereby given a structural height such that it can be actuated and its position indicated at the plane (36) of the ground by means (22) at the upper end of the pressure-free part.
