Abstract

A rough-in valve assembly comprising a valve body, wherein the valve body comprises a thermoplastic, the valve body comprises a first fluid inlet, a second fluid inlet, a first fluid outlet, and a second fluid outlet, the valve body comprises a valve chamber configured to receive a fluid mixing valve assembly, and the valve chamber is in fluid communication with the first fluid inlet, the second fluid inlet, the first fluid outlet, and the second fluid outlet. A rough-in valve body may comprise an engineering thermoplastic. A rough-in valve body may comprise an injection molded thermoplastic.

First claim

The invention claimed is:

1 . A rough-in valve assembly comprising a valve body, wherein
the valve body comprises a thermoplastic, the valve body comprises a first fluid inlet, a second fluid inlet, a first fluid outlet, and a second fluid outlet, the valve body comprises a valve chamber configured to receive a fluid mixing valve assembly, wherein the first fluid inlet, the second fluid inlet, the first fluid outlet, and the second fluid outlet each comprise one or more apertures configured to receive a fastener configured to couple to a nipple adapter, and the valve chamber is in fluid communication with the first fluid inlet, the second fluid inlet, the first fluid outlet, and the second fluid outlet.

2 . The rough-in valve assembly according to claim 1 , wherein the valve body comprises an injection molded thermoplastic.

3 . The rough-in valve assembly according to claim 1 , wherein the valve body comprises one or more engineering thermoplastics selected from polyamides, polyesters, polycarbonates, acrylonitrile-butadiene-styrene, and polyacetals.

4 . The rough-in valve assembly according to claim 1 , wherein the first fluid inlet, the second fluid inlet, the first fluid outlet, and the second fluid outlet each comprise an inner surface configured to receive and couple to a nipple adapter.

5 . The rough-in valve assembly according to claim 1 , wherein the first fluid inlet, the second fluid inlet, the first fluid outlet, and the second fluid outlet each comprise one or more slot-shaped apertures configured to receive a U-clip fastener configured to couple to a nipple adapter.

6 . The rough-in valve assembly according to claim 4 , wherein the nipple adapter is configured to swivel relative to the valve body.

7 . The rough-in valve assembly according to claim 1 , wherein the valve body comprises one or more openings configured to receive and couple to a service stop.

8 . The rough-in valve assembly according to claim 1 , wherein the valve body comprises one or more openings configured to receive and couple to a service stop, and wherein the one or more openings comprise one or more apertures configured to receive a fastener configured to couple to the service stop.

9 . The rough-in valve assembly according to claim 1 , wherein the valve body comprises one or more openings configured to receive and couple to a service stop, and wherein the one or more openings comprise one or more slot-shaped apertures configured to receive a U-clip fastener configured to couple to the service stop.

10 . The rough-in valve assembly according to claim 1 , wherein the first fluid inlet and the second fluid inlet are coaxial.

11 . The rough-in valve assembly according to claim 1 , wherein the first fluid outlet and the second fluid outlet are coaxial.

12 . The rough-in valve assembly according to claim 1 , wherein the first fluid inlet and the second fluid inlet share a central inlet axis, the first fluid outlet and the second fluid outlet share a central outlet axis, and the central inlet axis and the central outlet axis are perpendicular.

13 . The rough-in valve assembly according to claim 12 , wherein the central inlet axis and the central outlet axis intersect within the valve chamber.

14 . The rough-in valve assembly according to claim 1 , wherein the fluid mixing valve assembly comprises a pressure balance valve or a thermostatic valve.

15 . The rough-in valve assembly according to claim 1 , wherein the fluid mixing valve assembly comprises a manifold having a manifold chamber configured to receive a fluid mixing valve.

16 . The rough-in valve assembly according to claim 1 , comprising a fluid mixing valve assembly positioned in the valve chamber.

17 . The rough-in valve assembly according to claim 15 , wherein the fluid mixing valve assembly comprises the fluid mixing valve disposed in the manifold chamber.

18 . The rough-in valve assembly according to claim 1 , comprising a nipple adapter positioned in and coupled to one or more of the first fluid inlet, the second fluid inlet, the first fluid outlet, or the second fluid outlet.

19 . The rough-in valve assembly according to claim 1 , comprising a service stop positioned in and coupled to one or more openings of the valve body.
