4N-3297: 0.335" Outer Diameter Relief Valve Disk

A Relief Valve Disk is to regulate the pressure within the fuel unit. The primary function of the relief valve disk is to prevent excessive pressure buildup within the fuel filter. As fuel flows through the filter, it encounters resistance due to the filtration process. This resistance can lead to an increase in pressure within the filter housing. Attributes: • Allowing excess pressure to escape from the unit • Withstands the harsh conditions encountered in fuel unit Applications: A Relief Valve Disk maintains the optimal pressure levels within a fuel filter, ensuring efficient filtration and protecting the integrity of the fuel unit.
