A drain valve including a housing, a poppet, a seal, a follower pin, and a biasing mechanism. The housing defines a passage there-through from a first end to a second end, a cam surface at the second end with at least two detents therein, and at least one slot in the housing fluidly coupling the passage to exterior of the housing. The poppet is disposed within the passage. The seal is disposed between the housing and the poppet. The follower pin is coupled to the poppet near the poppet second end. The follower pin is configured to move along the cam surface and settle in at least one of the at least two detents. The spring is configured to bias the poppet away from the second end.

I claim: 1. A drain valve, comprising: a housing having a first end and a second end, wherein said housing defines an opening at said first end and a passage extending at least partially through said housing from said opening toward said second end; a cam surface coupled to said housing at a locati
I claim: 1. A drain valve, comprising: a housing having a first end and a second end, wherein said housing defines an opening at said first end and a passage extending at least partially through said housing from said opening toward said second end; a cam surface coupled to said housing at a location remote from said first end, where said cam surface includes at least two detents each located along said cam surface at different distances from said housing first end; a poppet configured to rotate and slide within said passage; a biasing mechanism coupled to said poppet and configured to bias said poppet away from said second end; and a follower pin coupled to said poppet and configured to travel along said cam surface and settle in said at least two detents. 2. The drain valve of claim 1, wherein said housing is a hollow cylinder extending between said first end and said second end, and said passage is a cylindrical passage extending through said housing from said first end to said second end. 3. The drain valve of claim 1, wherein said housing defines said cam surface at said second end. 4. The drain valve of claim 1, wherein said housing defines said cam surface between said first end and said second end. 5. The drain valve of claim 1, wherein said cam surface includes a third detent located along said cam surface at a different distance from said first end than said at least two detents. 6. The drain valve of claim 1, wherein said biasing mechanism is a spring. 7. The drain valve of claim 6, wherein said spring is disposed within said housing at least partially between said housing and said poppet. 8. The drain valve of claim 1, further comprising an annular insert within said opening. 9. The drain valve of claim 1, further comprising a seal coupled to said poppet such that said seal prevents fluid flow through said opening when said follower pin is in a closed detent of said at least two detents. 10. The drain valve of claim 1, further comprising a flange coupled to said housing at said first end, where said flange extends substantially perpendicular to said housing away from said opening. 11. The drain valve of claim 1, wherein said housing further defines at least one slot in said housing that allows fluid to flow through said at least one slot into said passage. 12. The drain valve of claim 1, further comprising another passage through said poppet. 13. A drain valve, comprising: a housing having a first end and a second end remote from said first end, wherein said housing defines: a passage through said housing from said first end to said second end; a cam surface at said second end with at least two detents therein; and at least one slot in said housing fluidly coupling said passage to exterior of said housing; a poppet disposed within said passage; a follower pin coupled substantially perpendicularly to said poppet, where said follower pin is configured to move along said cam surface and settle in said at least two detents; a biasing mechanism configured to bias said poppet away from said second end. 14. The drain valve of claim 13, wherein one of said at least two detents includes a closed detent configured to position said follower pin and said poppet in a position where fluid flow through said at least one slot is prevented by said seal and said poppet. 15. The drain valve of claim 13, wherein one of said at least two detents includes an open position detent configured to position said follower pin and said poppet in a position where fluid flow through said at least one slot is permitted. 16. The drain valve of claim 13, wherein each of said at least two detents are located along said cam surface at different distances from said housing first end. 17. The drain valve of claim 13, wherein said cam surface includes a third detent located along said cam surface at a different distance from said first end than said at least two detents. 18. The drain valve of claim 13, further comprising a seal disposed between said housing and said poppet. 19. The drain valve of claim 13, wherein said biasing mechanism is a spring. 20. The drain valve of claim 19, wherein said spring is disposed within said housing at least partially between said housing and said poppet.
