This internal DSV valve can be used for fuel tanks that have -12AN ORB female threads (including the Radium 20-049X-XX FCST). The high flowing -12AN male fitting permits dry break applications that use dump cans for quick fuel filling. The 1-piece machined part is manufactured from billet 6061 aluminum and type-II anodized. Included are 2 ball valves, FKM Viton O-ring, and a stainless steel retaining ring. These materials are compatible with all fuel types including alcohol fuels such as methanol and E85. It can easily be disassembled for quick cleaning, inspection, and maintenance.
