Low-profile valve assembly
Disclosed are low-profile valve assemblies for engaging a counter top or other mounting surface having a through opening. A special collar is provided which has a flange facing the outer surface of the mounting surface, and a skirt that extends into the through opening where the inward portion of the skirt connects to the valve body. This insets the valve body. o-ring and recess structures are provided to seal the construction, and a handle has an outer skirt to hide the collar.
1. A valve assembly mountable through a mounting surface that has an opening there through, the valve assembly comprising:
an elongated valve body having an internal bore mounting a control valve such that a valve control stem projects out of the valve body, wherein the elongated valve body also has a radially outer threaded periphery;
a collar having a flange extending essentially radially outward and a skirt extending axially from the flange, the skirt having threads adjacent a position axially remote from the flange which are suitable to mate with the outer threaded periphery of the elongated valve body, and the collar having an upper portion above the flange having radially directed threads thereon; and
a handle mountable to the control stem to control movement thereof;
wherein the collar is suitable to mount the valve body to the mounting surface with the flange facing an outward facing surface of the mounting surface while the skirt extends into the opening.
2. The valve assembly of claim 1 , wherein the flange is in a form of a circumferential ring.
3. The valve assembly of claim 1 , wherein the flange is in a form of a plurality of tabs.
4. The valve assembly of claim 1 , wherein the handle comprises an arm and an ornamental escutcheon linked to the arm for hiding the collar.
5. The valve assembly of claim 4 , wherein the collar has an externally threaded portion for coupling to the ornamental escutcheon.
6. The valve assembly of claim 4 , wherein the upper portion of the collar has internal threads for coupling to the ornamental escutcheon.
7. The valve assembly of claim 1 , wherein there is an o-ring between the collar and the valve body.
8. The valve assembly of claim 1 , wherein a control valve is threaded into the internal bore of the valve body, and the control valve is in a form of a valve cartridge.
9. A valve assembly mountable through a mounting surface that has an opening there through, the valve assembly comprising:
an elongated valve body having an internal bore mounting a control valve such that a valve control stem projects out of the valve body, wherein the elongated valve body also has a radially outer threaded periphery;
a collar having a flange extending essentially radially outward and a skirt extending axially from the flange, the skirt having threads adjacent a position axially remote from the flange which are suitable to mate with the outer threaded periphery of the elongated valve body; and
a handle mountable to the control stem to control movement thereof;
wherein the collar is suitable to mount the valve body to the mounting surface with the flange facing an outward facing surface of the mounting surface while the skirt extends into the opening, wherein the collar includes external threads.
