Outlet Flange Adaptors

For Roto-Disc Valves sizes 14-24″, the valve body discharge may be configured with a matching flange pattern without need for an adaptor.

Wedge Insert

The Wedge Insert option relieves the need for custom inlet flange.
The wedge is made of PTFE, UHMW, PEEK or other compatible thermo-plastic and is press-fit into the upstream flange, thereby eliminating any hang-up ledges.
