FBI used to cary them. they stopped but cando caries them now. they are good valves. they are fast. and loud. ive only seen one problem on one valve. and that was the diaphram tore, wich caused that valve to leak up. the diaphram is made from (in my opinion) a cheap rubber. the new FBI black powdercoated Blitzluft valves are very nice and are priced well too. they are a slight bit slower. from my own personal exprernces. but they are very reliable and you can get replacemnt parts for them. i had those apart too. due to rust from my air tank. but the internal workign are nicer. the diaphram is what looks to be a higher quality rubber. both are good valves all in all. the Black FBI valves offer mounting brackets. at the time when i had danz valves no bolt on brackets were avalible. hope that helps.
