What are PN10 and PN16?
PN10 and PN16 specify metric flange measurements (such as bolt circle diameter, hole size, bolt size etc) according to such standards as ISO 7005-1 or DIN 2501. Our standard flanges are defined in the English system (inches) and most will not mate up with metric flanges. With Kennedy Valve's state of the art CNC machining capabilities our products can have flanges made to PN10 or PN16 specifications so that a connection can be made between our products and metric products (for example, one of our valves with a PN10 flange end can be attached to some metric pipe that also has a PN10 flanged end).
