98 Wafer Ball Valve Series 2.0 & 3.0

Stainless Steel

The 98 Series wafer style ball valves are offered in CF8M (316) stainless steel. Gemini wafer ball valves combines efficient use of materials with application features that offer optimum value for many industrial valve applications. By installing a 98 Series valve between a pair of ANSI 150# or 300# Class raised face flanges the valve becomes a conventional three piece ball valve that meets ANSI B16.34 specifications for the rating of the flanges used. Not only does this help to minimize the cost, it also reduces the weight and space requirements over conventional flanged end valves.

Available with manual handle, pneumatic and electric actuators.
