American Standard’s high-efficiency urinal flush valves offer Selectronic hands-free function, flexible power options, reduced maintenance and reliable performance. Using 0.25 gal. per flush, these sensor-operated flush valves contribute to LEED points. Features include a self-cleaning piston with integral wiper spring, a fully mechanical manual override and chemical resistant EPDM seals. A fail-safe operation causes the valve to close automatically, and stay closed, upon loss of power or water pressure. Power options include exposed hard-wired AC, exposed hard-wired Multi-AC and exposed battery-powered configurations for installation flexibility.
