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