Spigot Valve End Connections

Spigot Valve End Connections. The type of socket used in the coupling or on the pipe end determines the form of the spigot ends. For cast iron pipes with lead joints the spigot end is provided with a raised band, for screwed and bolted gland and other forms of mechanical joint the spigot end is prepared to suit the joint. For asbestos cement connections, the spigot end is finished plain in the same way as the pipe. These spigot ends are normally associated with cast iron valves for water services in sizes 50mm and upwards.
