Solenoid valves

Performance and Control Through Engine Solenoid Valves

In this section of our online store, we offer an efficient selection of solenoid valves specifically designed to integrate into the engine systems of heavy-duty vehicles and industrial machinery. These electromechanical components are essential for automated fluid management, allowing precise control of air, fuel or oil flow according to the electronic control unit’s demands.

This catalogue is aimed at professional mechanics and transport companies seeking quality spare parts to maintain the operational reliability of their fleets. A solenoid valve in good condition ensures proper regulation of critical systems such as intake, turbocharging or exhaust gas recirculation, preventing unexpected downtime and optimizing vehicle consumption.

Technical criteria for choosing the appropriate replacement

• OEM reference: It is crucial to verify the manufacturer’s original part number to ensure full compatibility with the engine block.
• Coil voltage: Confirm whether the industrial vehicle’s electrical system operates at 12V or 24V before selecting the component.
• Fluid type: Ensure that the valve is designed for the specific medium it must control (diesel, compressed air, oil or coolant).
• Port configuration: Check the number of ways (inlets/outlets) and the type of physical connection to guarantee airtight installation without adaptations.
• Operating pressure: Verify that the replacement’s operating pressure range withstands the peaks generated by the engine system.

Frequently Asked Questions

What is the function of a solenoid valve in a heavy-duty vehicle engine?

Its main function is to open, close or divert the flow of liquids and gases through an electrical signal. In the context of industrial vehicles, they are vital for activating the engine brake, regulating turbocharger geometry, managing the injection system or controlling the cooling fan clutch.

What are the common symptoms of failure in these valves?

Malfunction typically manifests as engine power loss, unstable idle or activation of warning lights on the dashboard. Audible air leaks or fluid stains around the valve body may also be detected if the internal seals have failed.

Are truck solenoid valves universal?

No, these components are not universally interchangeable. Each system requires very specific technical specifications in terms of flow rate, electrical resistance and mounting points. Installing an incompatible reference may cause damage to the control unit or improper operation of pneumatic and hydraulic systems.

Is it advisable to clean a clogged solenoid valve or replace it?

Although cleaning may sometimes resolve minor blockages, in professional environments replacement with a new unit is recommended. Wear of internal components and electrical windings is often irreversible, so replacement ensures reliability and prevents recurring short-term failures.
