Pressure Regulators

The increasing demands for fuel system performance have driven the development of a new type of fuel pressure regulator that provides greater robustness in service along with excellent operational characteristics.

Fuel pressure regulator devices are connected to the fuel rail to balance and keep the pressure in the fuel system.

This keeps the injectors at constant pressure through a spring-loaded membrane which allows the opening of the return-flow channel.

The valve uncovers a fuel line that returns excess fuel to the fuel tank when it is opened by excessive pressure in the fuel lines.
