The Ultima Selectronic® Touchless Toilet Flush Valve from American Standard is designed for facilities seeking ADA-compliant, reliable, and hygienic commercial bathroom essentials. It meets ADA clearance requirements when installed under a grab bar at 36" height, ensuring accessible operation. The self-cleaning piston design and integral wiper spring prevent clogs and valve run-on, reducing routine maintenance and saving time and money. Touch-free operation helps maintain cleanliness and hygiene in high-use restrooms, while fully mechanical manual override allows flushing without power. Equipped with CR-P2 lithium battery (4-year life assuming 4,000 flushes per month), adjustable sanitary flush, chemical-resistant EPDM seals, and programmable Selectronic® Proximity System, the valve ensures extraordinary performance and reliable operation even with poor water quality. The valve automatically closes upon loss of power or water pressure and can be installed left- or right-handed. Fits 11½" rough-in bowls with 1½" top spud. This flush valve offers hands-free flushing with touchless operation for a hygienic bathroom with low maintenance requirements. CALGreen compliant for sustainability. Material: Brass.
