Integrated manifold and valve assembly
An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

wherein the assembly top is configured to be separated from the water valve body by a manifold.
2. The valve assembly of claim 1 , wherein the air valve actuator is disposed adjacent the water valve actuator.
3. The valve assembly of claim 1 , wherein the water valve body includes a water valve comprising a disc rigidly attached to a first rotatable shaft at a nonperpendicular angle, such that the disc is rotatable between at least a first position, wherein the disc prevents fluid communication between the water inlet and the first water outlet, and a second position, wherein the disc prevents fluid communication between the water inlet and the second water outlet.
4. The valve assembly of claim 3 , wherein the disc is further rotatable to and from a plurality of intermediate positions wherein the disc diverts a first portion of a water stream entering the water valve body at the water inlet to the first water outlet, and diverts a second portion of the water stream to the second water outlet.
5. The valve assembly of claim 3 , wherein the first rotatable shaft extends outside the water valve body and is configured to extend at least partially through a manifold water conduit.
6. The valve assembly of claim 1 , wherein the air valve includes an air valve member having a wall portion and an open portion, and the air valve member is rigidly attached to a second rotatable shaft, such that the air valve member is rotatable between at least a first position wherein the wall portion overlaps the air inlet substantially completely and a second position wherein the open portion overlaps the air inlet substantially completely, and wherein the air valve member is further rotatable to and from a plurality of intermediate positions wherein the wall portion partially overlaps the air inlet.
7. A valve assembly comprising:
a water valve including a water valve body having a water inlet and first and second water outlets;
a water-valve actuator configured to actuate the water valve;
an air valve including an air valve body having an air inlet and an air outlet;
an air-valve actuator configured to actuate the air valve;
first and second air channels attached to the water valve body; and
an air coupler configured to provide fluid communication between the air valve body and the first and second air channels;
wherein the water-valve actuator, the air valve, and the air-valve actuator are all disposed in an assembly top which is configured to be separated from the water valve by a manifold.
8. The assembly of claim 7 , wherein the air-valve actuator is disposed adjacent the water-valve actuator.
9. The assembly of claim 7 , wherein the water valve includes a water-valve shaft rigidly connected at a first end to the water-valve actuator and rigidly connected at a second end to a disc configured to selectively divert first and second portions of the stream of water.
10. The assembly of claim 7 , wherein the first and second air channels are configured to couple with first and second manifold air channels.
11. The assembly of claim 7 , wherein the air coupler is disposed in the assembly top.
12. A valve assembly for a hot tub, the assembly comprising:
a water valve body having a water inlet and first and second water outlets;
first and second air channels attached to the water valve body;
a pair of dual-extrusion manifolds, each coupled releasably to the water valve body; and
an assembly top comprising an air valve having an air inlet and an air outlet, and an air coupler configured to couple the first and second air channels to the air inlet.
13. The assembly of claim 12 , wherein the water valve body comprises a disc rigidly attached to a first rotatable shaft at a nonperpendicular angle, such that the disc is rotatable between at least a first position, wherein the disc prevents fluid communication between the water inlet and a first one of the water outlets, and a second position, wherein the disc prevents fluid communication between the water inlet and a second one of the water outlets.
14. The assembly of claim 13 , wherein the disc is further rotatable to and from a plurality of intermediate positions wherein the disc diverts a first portion of a water stream entering the water valve body at the water inlet to the first outlet, and diverts a second portion of the water stream to the second outlet.
15. The assembly of claim 13 , wherein the first rotatable shaft extends outside the water valve body and is configured to extend at least partially through a manifold water conduit.
16. The assembly of claim 13 , wherein the air valve includes an air valve member having a wall portion and an open portion, and the air valve member is rigidly attached to a second rotatable shaft, such that the air valve member is rotatable between at least a first position wherein the wall portion overlaps the air inlet substantially completely and a second position wherein the open portion overlaps the air inlet substantially completely.
17. The assembly of claim 16 , wherein the air valve member is further rotatable to and from a plurality of intermediate positions wherein the wall portion partially overlaps the air inlet.
18. The assembly of claim 16 , wherein the first and second rotatable shafts are substantially parallel to each other and each extend to the assembly top.
