The Crown® II Piston Flushometer, designed for "green" environments, is now available with new aesthetics from Sloan Valve Co. The Crown II is designed with a new handle assembly and an outside cover with accent rings offered with special finishes including brushed nickel, lustre gold, polished brass and satin. The inside cover isolates the threads from the water source to ensure uninterrupted performance. Sloan's patented piston Flushometer incorporates stainless steel materials, high-copper low-zinc brass castings and a single, cleanable filter. The Crown II also includes an engineered thermoplastic piston assembly that is easily replaced, compared to clog-prone brass pistons.Sloan Valve Co.
