Radium Engineering DSV 12AN ORB To 8AN Male - STD Fill

NOTE: Be sure to lubricate the Viton O-ring prior to installing either DSV valve.

FEATURES
Fuel Tank Venting

Once the tank is filled with fuel, the upper sealing ball valve floats to the top of the internal DSV chamber shutting off the air source. This safely prevents fuel from traveling up and out of the fuel cell vent line.
Roll Over Protection

In case of an accident in which the wheels are up-ended, the lower stainless steel ball holds the ball valve down sealing the vent. This safely prevents fuel from leaking out of the fuel cell vent line.

Notes

DSV and filler height relationship: The vertical height of the top (shut-off) ball in the dynamic safety valve should be positioned lower than the highest point of the fuel fill point.Filler and vent height relationship: The vertical height of at least one portion of the vent tubing (not included) should be positioned above the highest point of the fuel fill point.
