Boiler Valve Types - ohheating.c

A reduced bore valve has a smaller valve opening than the diameter of the pipe. A full bore valve's opening has the same diameter of the piping. These are used because they minimize the pressure drop across the valve. Butterfly Valves A butterfly valve regulates the flow through a disc-type element held in place in the center of the valve by a rod.
