A Duplex Fuel Filter Control Valve is used in diesel engines to regulate the flow of fuel through two separate fuel filters. The valve controls the flow of fuel through each filter based on the pressure differential between them, allowing both filters to function when the pressure is within a specified range and diverting fuel flow to the filter with the lower pressure when the pressure differential exceeds a certain threshold.

Attributes:
• Allows for uninterrupted fuel flow to the engine during filter servicing.
• Improved filtration of fuel, which helps to protect the engine from contaminants.

Applications:
The Duplex Fuel Filter Control Valve acts as a switching valve, allowing the engine to switch between the two filter elements in the Duplex fuel filter.
