All gate valves are constructed of ductile iron. The spigot inlet of the valve is designed to insert into a gasket bell end. The gasket bell outlet is designed to push on to IPS (iron pipe size) plastic pipe. The pipe end must be beveled and lubricated with gasket pipe lube before inserting into the gasket bell end. The bell end has a factory installed pipe to fitting joint restraint to eliminate the need for thrust blocking.
