Electric valves are important components for switching and control as well as performing comfort and safety functions. They are used for the purpose of operating pneumatic actuators or for switching between two or more states.
Valves offer great potential for the independent aftermarket as they can be monitored by the OBD system directly or indirectly. If these valves fail, replacement is essential. Trust the OE quality of Pierburg, the market leader with an OE production of over 125,000 valves per day and more than 350 types of valves in series production.
For controlling pneumatic EGR valves, regulating throttles and VTG turbochargers.
Toggle valves are used wherever a simple open-close function of pneumatic actuators is required, for example to actuate secondary air valves, intake manifold valves and bypass valves on EGR coolers. However, they can also be used in clock control, e.g. pressure relief valves (wastegate).
Active Carbon Valves (ACF Valves)
ACF valves are important components in the fuel tank vent system as well as for diagnosing fuel tank leaks.
The fuel tank ventilation system stops fuel vapors containing harmful hydrocarbons from escaping into the atmosphere. It also provides air to the fuel tank, for example if a vacuum forms in the tank when fuel levels drop or the ambient temperature is low.
Recirculating air valve
The recirculating air pressure control valve prevents unnecessary deceleration of the turbocharger when the throttle is suddenly opened. This greatly reduces the effect of turbo lag.
Control and solenoid valves for adjusting the camshaft
Depending on the engine speed, the control valves direct the flow of oil through different oil channels to the corresponding chambers in the hydraulic camshaft adjuster. As a result, the camshaft rotates relative to its axis and the timing of the gas distribution changes. This improves operating behavior at full and partial load and reduces fuel consumption.
