The Falcon High Performance Key-Valve® (HPKV®) is Enswico compatible and is used in urinals retrofitted to convert them to waterless or low flush operation. It is the most robust, high performance dry valve on the market. Through the patent-pending Bell Valve, Falcon's HPKV® technology provides safe, long lasting, low odour performance. Falcon's Key-Valve® description.
Since the introduction of the original Key-Valve® technology, there have been many improvements incorporated into the design that sets Falcon cartridges apart from the rest. The latest design follows that same path and includes patent-pending features to provide the best sealing, flow and anti odour performance.
