3. The flushometer system of claim 2 , wherein the plurality of bosses include at least one vacuum breaker boss and at least one tool receiving boss.
4. The flushometer system of claim 1 , wherein the valve body includes an inlet aperture adjacent the valve seat assembly and a venting journal adjacent to the sleeve and the outlet.
5. The flushometer system of claim 1 , wherein the valve seat assembly comprises a valve inlet and a plurality of valve outlets.
6. The flushometer system of claim 5 , wherein the valve seat assembly is has a cylindrical shape with the valve inlet on a first planar face and the plurality of main valve outlets disposed about a curved surface.
7. The flushometer system of claim 5 , wherein the flow control portion's snubber portion is positioned adjacent the piston assembly with the flush profile portion extending therefrom and the flow control terminating with the plug portion extending from the flush profile portion.
8. The flushometer system of claim 5 wherein an outer diameter of the snubber portion is greater than an inner diameter of the valve inlet, an outer diameter of the plug portion is less than the inner diameter of the valve inlet and an outer diameter of the flush profile portion is less than the outer diameter of the plug portion.
9. A concealed flushometer system comprising:
a valve body having an inlet, an outlet, and an actuation opening;
a valve seat assembly disposed in the valve body between the inlet and the outlet;
a sleeve adjustably engageable with the valve body, the sleeve movable relative to the valve body to be engaged and disengaged from the valve seat assembly;
a piston valve assembly disposable within the sleeve and configured to engage the valve seat assembly to close the flushometer system;
an actuation module engageable with the sleeve and having a relief valve, the actuation module secured at the actuation opening with a locking mechanism;
a face plate assembly having a face plate push button and a mounting ring, the mounting ring configured to engage a structure behind which the valve body is positioned,
the mounting ring further includes mounting ring opening through which a face plate is engageable with the relief valve.
10. The concealed flushometer system of claim 9 , wherein the mounting ring opening has an inner diameter larger than the outer diameter of the actuation opening of the valve body.
11. The concealed flushometer system of claim 9 , wherein the face plate includes a face plate actuation surface for engaging the relief valve.
12. The concealed flushometer system of claim 9 , wherein the relief valve includes a relief valve stem adjustment mechanism that is extendable relative to the valve body.
13. The concealed flushometer system of claim 9 , wherein the face plate is pivotally mounted with regard to the mounting ring such that the face plate pivots about a hinge towards the valve body to engage the relief valve and is pivotably away from the valve body to expose the actuation module through the mounting ring opening.
14. A flushometer system comprising:
a valve body having an inlet, an outlet, and an actuation opening;
a valve seat assembly disposed in the valve body between the inlet and the outlet;
a sleeve adjustably engageable with the valve body, the sleeve movable relative to the valve body to be engaged and disengaged from the valve seat assembly;
an actuation module engageable with the sleeve, the actuation module secured at the actuation opening with a locking mechanism;
a flow control disposable within the sleeve and configured to engage the valve seat assembly to close the flushometer system, the flow control in communication and controlled by the actuation module; and
the locking mechanism engageable with a shoulder disposed adjacent the actuation opening, the locking mechanism at least partially captured between the shoulder of the valve body and the actuation module when the sleeve is spaced apart from the valve seat assembly and the locking mechanism being disengaged from the actuation module when the sleeve is engaged with the valve seat assembly.
15. The flushometer system of claim 14 , wherein the actuation module includes an automatic actuation.
16. The flushometer system of claim 15 , wherein the automatic actuation module includes a solenoid.
17. The flushometer of claim 15 , wherein the actuation module includes a piston assembly slidably disposed within the sleeve and affixed to the flow control at one end and positioned between the flow control and the actuation module defining an upper chamber there between, the piston assembly having a by-pass orifice providing fluid communication between the inlet and the upper chamber.
18. The flushometer system of claim 14 , wherein the actuation module includes a activation module passage there through and a relief valve stem slidably positioned in the activation module passage with a lower stem cap sealing a upper chamber from the outlet.
19. The flushometer system of claim 18 , wherein the relief valve stem having a flow portion that is slidably engageable with a vent opening in the activation module passage wherein the vent opening is in communication with the outlet.
20. The flushometer system of claim 14 , wherein the sleeve is threadably engaged with the valve body.
