Each model is available in either the 106 Series Full Port or 206 Series Reduced Port. The 206 Series is similar to the 106 Series except that the seats are one standard pipe size smaller than the flange sizes. For example, a 6 in / 150 mm 206-PG valve has a 4 in / 100 mm seat diameter.
Most valves are available in Angle Pattern. Valves larger than 6 in / 150 mm are also available with the Single Rolling Diaphragm technology.
