American Standard Ultima Selectronic Exposed Urinal Flush Valve, Diaphragm Type, Base Model, 0.125 gpf/0.5 Lpf - AMS-624B013

It's a urinal flush valve. The 624B013 is the exposed Selectronic diaphragm-type valve rated at 0.125 gpf / 0.5 Lpf, which is a urinal flush volume, not a toilet volume. If you're specifying for a water closet you need a different valve in the Selectronic diaphragm family. Note that the catalog attribute for application on this item reads Toilet, which is the broad restroom-fixture grouping; the valve itself is built for urinal service.

Only if the fixture is designed for a pint flush. The 624B013 delivers 0.125 gpf (0.5 Lpf), an eighth of a gallon, and putting that volume on a urinal bowl engineered for 1.0 gpf or 0.5 gpf will usually leave the trap under-scoured and cause odor and staining complaints. Match the valve volume to the volume stamped on the fixture. If your urinals are 0.5 gpf or 1.0 gpf, order the Selectronic valve at that rating instead.

Exposed. The valve body mounts out in front of the wall on the urinal supply, with the sensor in the valve housing itself, so there's no need to open the wall or provide an access panel. If your drawings call for a concealed valve with a wall-plate sensor, this is not that product.

Diaphragm. The 624B013 is a diaphragm-type valve, part of American Standard's Selectronic diaphragm flush valve family. That matters for maintenance stocking: the rebuild part is a diaphragm kit, not a piston assembly, so if your facility already standardizes on diaphragm valves the repair kits on your shelf are the right family.

Yes, if every urinal in the building is a 0.125 gpf pint fixture. The 624B013 ships as a single configuration, chrome, part 624B013.002, so a repeat order is unambiguous and every valve on the floor takes the same diaphragm rebuild kit. Where a building has mixed flush volumes, split the order by rating instead of forcing one valve everywhere.

Chrome is the only finish offered on the 624B013, ordered as part number 624B013.002. If a job specifies a brushed nickel or matte black exposed urinal valve, you'll need a different American Standard model number.

Base model is the standard Selectronic configuration of this exposed urinal valve at 0.125 gpf, without the added feature options American Standard offers on upgraded versions of the same diaphragm platform. If a spec calls out a specific added function on the valve, confirm the model number on the submittal matches, because base model and the optioned versions carry different part numbers even though the valve body and 0.125 gpf flush volume are the same.
