Flanged Natural Gas Ball Valves
Reducing Flanged Natural Gas Ball Valve
A reducing flanged natural gas ball valve with the ball bore one size smaller than the pipe internal diameter, featuring a ductile iron body and stainless steel ball in a 3-piece configuration. Thanks to the smaller ball and body, it is lighter and more economical than full bore models.
Available from DN32 to DN300; in smaller sizes PN40, and from DN125 onwards PN25 pressure class. Used in natural gas distribution and installation lines where a small pressure drop in flow is acceptable.
