From the Manufacturer
TOTO, the world leader in advanced plumbing systems, provides sensor operated flush valves for facilities demanding the finest sanitation equipment for busy restrooms. “Hands-free” technology effectively reduces unsanitary conditions from unflushed fixtures. TOTO’s new technology of automatic generator flush valves offers easy installation without the cost and downtime required to install power supplies and wiring for each valve. A hydro-powered turbine charges the power supply during usage, eliminating the need for a battery replacement or consumption of external power for up to 10 years. TOTO’s piston valve technology is a marked improvement over traditional rubber diaphragm type valves. Longer piston travel and a self-cleaning stainless steel screen to capture debris reduces common problems such as continuous running and flooding. The piston seat itself will not warp or misseal, reducing repair and maintenance costs. A micro-porous cup seal keeps the piston self-lubricated upon each activation with the incoming water supply.
