Product Description The Selectronic Urinal Flush Valve from American Standard is designed for facility managers and commercial restroom operators who need a reliable, low-maintenance solution for high-traffic restrooms. This touch-free flush valve features a self-cleaning piston that reduces clogging and prevents valve run-on, saving time and money on routine maintenance. With an integral pressure compensation feature, the sensor activated valve maintains accurate flush volume regardless of inlet water pressure. Installed easily on 3/4" top-spud urinals with an 11-1/2" rough-in, the unit comes with a CR-P2 lithium battery (4-year life at 4,000 flushes/month) and is equipped with a fully programmable Selectronic Proximity System for custom settings. The valve also includes a manual override button, fail-safe operation, adjustable sanitary flush that limits the spread of germs, and chemical-resistant EPDM seals for extended durability.
