Radium DSV 12AN ORB To 12AN Male - Quick Fill (Internal)

Radium DSV 12AN ORB To 12AN Male - Quick Fill (Internal)

Application: Radium FCST, FCST-X and other fuel tanks/cells with a 12AN ORB female vent port, used with a dry break refuelling system
Part Type: Dynamic Safety Valve (DSV), low fill – internal
Part Number: 20-0535

The Radium Engineering Dynamic Safety Valve (DSV) is a quick-fill vent valve that must be used when a dry break refuelling system is added to a Radium FCST, FCST-X or any fuel cell or tank with a 12AN ORB female vent port. It performs two jobs: it shuts off the vent when the tank is full, and it provides roll-over protection.

When the tank fills, the upper sealing ball floats up and closes the vent so fuel cannot rise into the vent line. A small amount of air pressure then builds in the cell and the dump can begins to "chug", signalling that the cell is full and the dry break can be released – so there is no need to watch the filling process. This low fill version suits fuel cells with a small width-by-length footprint and a shorter height to the filler, shutting off venting sooner to prevent overfilling. It is machined in one piece from billet 6061 aluminium with a Type-II anodised finish.

Key Features

• Automatic Shut-Off: Floating ball closes the vent when the tank is full
• Roll-Over Protection: Prevents fuel escaping through the vent
• Low Fill Shut-Off: Suits small-footprint or short-filler fuel cells
• One-Piece Billet: 6061 aluminium, Type-II anodised
• Serviceable: Can be disassembled for cleaning, inspection and maintenance
• Fuel Compatibility: All fuel types including methanol and E85

Optional Parts

• Radium DSV, 12AN ORB to 12AN Male, High Fill (20-0935) – high fill DSV – choose instead for larger cells or high remote fillers
• Radium DSV Valve Extension Adapter (20-1035) – extension adapter that moves the shut-off point higher
• Radium Dry Break, 1.5In, Female, Vented (20-0549-V) – vented 1.5in female dry break receiver
• Radium Engineering Roll Over Valve - 12AN ORB to 8AN Male (20-0934) – roll-over valve to use instead with standard-style fuel fillers

Important Notes

• Internally mounted DSV designed for use with pressureless "vented" dry break receivers
• The top (shut-off) ball must sit lower than the highest point of the fuel fill point
• At least one section of vent tubing (not included) must sit above the highest point of the fuel fill point
• Do not use a DSV with standard-style fuel fillers – use the 20-0934 roll-over valve instead
• Not compatible with very early 20-014X-XX FCST units, which have 8AN ORB vent ports only
• If fuel ejects from the dry break receiver vent during or after refuelling, the shut-off point is too high

Vehicle Fitment

• Radium FCST and FCST-X fuel cell surge tanks (12AN ORB vent port)
• Other fuel tanks/cells with a 12AN ORB female vent port
