БЛОК КЛАПАНА ЭЛЕКТРОМАГНИТНОГО Caterpillar 4349010

The Fuel Overflow Solenoid Valve regulates the return flow of excess fuel from the fuel system by opening or closing based on an electrical signal sent to the solenoid. When activated, the valve directs overflow fuel back to the designated return line, helping maintain proper fuel pressure at the injectors or fuel rail. When de‑energized, the valve prevents unwanted backflow or uncontrolled fuel movement. The controlled operation helps balance pressure during cold starts, high‑load conditions, or rapid fuel demand changes.Attributes:• Controls excess fuel return flow using solenoid activation.• Helps maintain stable fuel pressure across operating conditions.• Prevents uncontrolled overflow in the fuel circuit.• Particles must not exceed a major dimension of 0.3 mm or a minor dimension of 0.2 mm.• Volumes and surfaces not exposed to working fluid in the application are exempt from this specification.Applications: The Fuel Overflow Solenoid Valve is installed in fuel return circuits to regulate the flow of excess fuel back to the return line. It helps maintain correct fuel pressure, prevent overflow, and support consistent fuel system performance under changing operating conditions.
