Abstract

A valve for a fuel tank is provided, comprising a housing configured with a float chamber and a disk chamber being in flow communication through an intermediate flow path. The disk chamber is configured with a fluid outlet port from the intermediate flow path and a valve outlet and a fluid inlet port is sealable by a sealing member of a float member axially displaceable within the float chamber to selectively facilitate fluid flow to or from the float chamber via the valve. The fluid outlet port is sealable by a pressure holding member axially having an under pressure bleed valve displaceable between a sealed position wherein the under pressure bleed valve is sealed, and an open position wherein the under pressure bleed valve is open, providing passage of fluid therethrough.
