Shut=off valve assembly for steam heating system

摘要

The valve assembly consists of a main channel (11) onto which are laterally connected several condensate return pipes, each one containing two shut-off valves (17.2,20) separated by a purging line (15). The main channel has lateral secondary channels (10) forming a coplanar group (B-C) of secondary channels. The operating shafts (13) of the two shut-off valves are aligned on each secondary channel. Each secondary channel is provided with two lateral connectors, one for the purging line (15) and other for the condensate return pipe (16), located on the same side of the plane made up of the coplanar group (B-C) of the secondary channels.
