American Standard Ultima Selectronic Exposed Urinal Flush Valve, Diaphragm Type, Battery, 0.125 gpf/0.5 Lpf - AMS-6245013

Battery powered, no hardwiring or transformer needed. It ships with a CR-P2 lithium battery rated for four years of service at roughly 4,000 uses per month, so a low-traffic restroom stretches further and a high-traffic one runs shorter. That makes it a practical retrofit where there is no power at the fixture.

It flushes at 0.125 gpf (0.5 Lpf), which is the pint-flush rate used for high-efficiency urinals. Pair it with a urinal fixture actually rated to evacuate at 0.125 gpf. Dropping a pint valve onto an older 1.0 or 1.5 gpf bowl that wasn't designed for it is the usual cause of drain-line and carry complaints.

Yes. The tailpiece is adjustable and the valve can be set up left- or right-handed, so it works off a supply stub on either side and gives some slack on rough-in dimensions that aren't perfect.

There is a fully mechanical manual override button on the valve that flushes it without power. For a property manager that means a dead battery is a maintenance ticket, not an out-of-service fixture, and staff can still flush by hand until the CR-P2 is swapped.

This Ultima Selectronic is a diaphragm type. Diaphragm valves are the common commercial choice and are more tolerant of the water conditions in most municipal systems; piston valves are generally chosen where water is dirty or heavily sedimented. American Standard uses an EvoLast diaphragm here, a material made to resist chlorine and chloramine so it doesn't harden and fail early on chloraminated municipal water.

Run-on usually traces to a clogged refill orifice in the diaphragm. This valve uses DynaClean, an integral wiper spring that scrubs that orifice on every single flush, so debris doesn't build up and hold the valve open. It's the feature worth knowing about if you're standardizing a building after chasing running urinals.

Yes. Detection range is adjustable manually at the valve, or with an optional remote control that American Standard sells separately. Handy in tight stall layouts or where foot traffic passes close enough to trip the sensor.

It's supplied in polished chrome, manufacturer part number 6245013.002. Chrome is the only finish offered for this exposed battery model, which is the finish most commercial restroom specs call for anyway.

The body is a proprietary brass alloy that American Standard specifies as dezincification resistant, so it won't suffer the zinc leaching and porous failures that plague ordinary yellow brass on aggressive or softened water supplies.
