American Standard 6063505.002 is an exposed, battery-powered, sensor-operated urinal flush valve designed for 3/4" top spud urinals. It features a self-cleaning piston operation to help prevent clogging and reduce maintenance, and a positive seal to ensure leak-free performance. The range can be adjusted manually or by remote control, and the sensor and electronic controls are fully enclosed and water-resistant. It also has a fully mechanical manual override button for flushing during a power outage, and automatically flushes after 24 hours of non-use to maintain the trap seal.
