Abstract
A rotary valve includes a valve body including an opening formed therein, a rotary component received within the opening of the valve body with the rotary component configured to rotate relative to the valve body about an axis of rotation thereof, and a sealing assembly including a hard sealing structure and a soft sealing structure disposed between the valve body and the rotary component. The hard sealing structure is formed from a substantially rigid material and is configured to sealingly engage the rotary component. The soft sealing structure is formed from a resiliently deformable material and is configured to sealingly engage the hard sealing structure and the valve body.
