Valve system with circumferentially oriented flow

A valve system, comprising:

• a valve seat having a crenulated portion, the crenulated portion having an annular recess and a plurality of teeth that are separated by a plurality of circumferential gaps, at least one of the plurality of teeth having an angled surface that borders between one of the plurality of circumferential gaps and the respective one of the plurality of teeth, the angled surface being oriented at an angle with respect to an axis that extends radially outwardly from a central axis of the valve seat;
• an outlet passage located downstream of the valve seat for directing flow out of the valve assembly;
• a control valve having a control valve disk that is moveable in a direction towards the valve seat and in a direction away from the valve seat, the control valve disk and the valve seat cooperating together to modulate flow exiting the outlet passage;
• and
• a stop valve located within the annular recess of the crenulated portion, the stop valve having a stop valve stem and a stop valve seat, the stop valve seat selectively sealing against the valve seat, and the angled surface of the at least one of the plurality of teeth orienting flow in a generally circumferential away from the valve stem and downstream of the stop valve disk.
