Sloan Valve Company has announced the availability of a retrofit valve kit that can be used to convert the company's manual Royal Flushometer to a battery-powered Optima Plus Flushometer within minutes. Sloan's Optima Plus Flushometer is a completely self-contained flushing system that uses an infrared sensor to detect the presence of the user and automatically flush after every use. The system needs no AC hookups and can be used in any retrofit or new construction application. The Royal RESS Retrofit Kit requires only one trade installation and includes: a patented dual filtered fixed bypass diaphragm that helps prevent valve run-on and ensures extended Flushometer performance; an impact-resistant plastic cover housing four supplied AA Duracell batteries, the sensor and the self-diagnostic circuitry for operation; and a chrome-plated brass locking ring.Sloan Valve Company.
