Product Overview
Our 12mm Vent Float Valve is designed to provide precise fuel venting control in fuel systems using RP-3 fuel. The valve ensures complete closure when the liquid level drops below a certain threshold (36mm below the mounting hole axis), effectively preventing fuel leakage under low-pressure conditions. With a temperature range of -55℃ to +70℃, it delivers reliable performance across various operating environments.
