A valve system is provided including a valve seat, an outlet passage and a stop valve. The valve seat has a crenulated portion. The crenulated portion has an annular recess and a plurality of teeth that are separated by a plurality of circumferential gaps. At least one of the teeth has 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 is oriented at an angle with respect to an axis that extends radially outwardly from a central axis of the valve seat. The outlet passage is located downstream of the valve seat for directing flow out of the valve assembly. The stop valve is located within the annular recess of the crenulated portion.

The valve system of claim 11, wherein the control valve disk selectively seals against the valve seat. 13. The valve system of claim 11, wherein a quantity of fluid passes through a channel located between the control valve disk and the circumferential gaps of the crenulated portion of the valve seat. 14. The valve system of claim 13, wherein another quantity of fluid passes between an upper surface of the plurality of teeth and the control valve disk. 15. The valve system of claim 14, wherein the quantity of fluid and the another quantity of fluid flow into the recess of the crenulated portion of the valve seat and exit the valve assembly through the flow outlet. 16. The valve system of claim 11, wherein the angle has dimensions higher than about zero degrees and lower than about ninety degrees. 17. The valve system of claim 11, wherein the valve system directs steam out of the outlet passage of the valve assembly. 18. 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, the angle having dimensions higher than about zero degrees and lower than about ninety degrees;an outlet passage located downstream of the valve seat for directing steam 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 steam exiting the outlet passage, and the control valve disk selectively sealing against the valve seat; anda 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 steam in a generally circumferential away from the valve stem and downstream of the stop valve disk. 19. The valve system of claim 18, wherein a quantity of fluid passes through a channel located between the control valve disk and the circumferential gaps of the crenulated portion of the valve seat. 20. The valve system of claim 19, wherein another quantity of fluid passes between an upper surface of the plurality of teeth and the control valve disk.
