Ductile Iron Sluice Valve
Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spherulitic graphite cast iron and SG iron, is a type of cast iron invented in 1943 by Keith Millis.
Nodular or spheroidal graphite cast iron produced by residual magnesium remaining in the iron after ladle addition of magnesium.
molten iron treated with an element such as magnesium or cerium to induce a measurable degree of ductility to the metal; these additives do not affect galvanizeability
A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid.
sluicegate: regulator consisting of a valve or gate that controls the rate of water flow through a sluice

Went out to a jobsite on 3/18 with a few of the guys from work to watch some 36" water line being installed. I had never seen that large of a water line be installed before pretty cool stuff. This is the bell end of a joint of ductile iron pipe.
