Due to the relatively smooth transition between the sealing surface and the interior, whether open or closed, globe valves are frequently employed. A216WCB/F6 is the standard material. Requests for different materials and trimmings will be accommodated. A reduction gear is available and is actuated by a hand wheel. A mirror finish is achieved by grinding and lapping the seat ring and wedge disc, creating identical sealing surfaces.
