Valves offer great potential for the independent spare parts trade, since they can be monitored by the OBD system either directly orindirectly. If these valves fail, replacement is essential. Trust theOE quality of Pierburg, the market leader with an OE production ofover 125,000 valves a day and more than 350 valves in seriesproduction.
PRESSURE TRANSDUCERS
For continuous control of pneumatic EGR valves, regulating throttles and VTG turbochargers.
Motorservice supplies 86 articles covering over 110 million vehicles.
SWITCHOVER VALVES
Switchover valves are used wherever a simple open-close function is needed for pneumatic actuators, e.g. to actuatesecondary air valves, intake manifold flaps and bypass flaps on EGR coolers.However, they can also use clocked control, e.g. for boost pressure valves (wastegate).

ACTIVATED CARBON FILTER VALVES (ACF VALVES)
ACF valves are important components in the fuel tank ventilation system as well as the fuel tank leakage diagnosis.
The fuel tank ventilation system stops fuel vapours 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 fall or the ambient temperature is low.
Motorservice supplies 11 articles covering over 10 million vehicles.
RECIRCULATING AIR VALVE
The recirculating air valve for boost pressure control prevents the turbocharger from slowing down unnecessarily when the throttle valve closes suddenly. This reduces the turbo lag effect significantly.

CONTROL VALVES AND CENTRAL MAGNETS FOR CAMSHAFT ADJUSTMENT
Depending on the engine speed, the control valves guide the oil flow through various oil channels to the respective chambers in the hydraulic camshaft adjuster. As a result, the camshaft is turned relative to the camshaft gear and the control times are altered. This improves operating behaviour under full load and part load, and reduces fuel consumption.
