Patented brass butterfly valves

RBB has launched few years ago the patented brass butterfly valve. Comparing with other valves as ball, globe and gate the butterfly performs just better. In fact the unique throttling device doesn't allow any accidental opening & closing while the special lever handle delivers the adjustement of the flow and to memorize its rate. Finally it's very cost effective and the unique shape of the liner means 10 times longer lifetime still in comparison with the other valves. The range is available in 10 options and the sizes are between 1/2" and 4".
