Socket Valve End Connections

Socket Valve End Connections. The ends of the valve are socketed to receive the plain spigot end of the pipe, the seal being made by the insertion of a yarn ring joint, corked with lead. Other forms of socket ends use a rubber scaling ring. These ends are either in the style of flange and socket adaptors for bolting to flanged end valves, or incorporated in the valves. Socket ends are normally associated with cast iron valves for water services in sizes 50mm and upwards.
