INA Central Valve

Product description:

Central valves have the task of moving the camshaft phasing unit to the desired adjustment position using defined amounts of oil volume. The purely mechanical components are actuated by a central magnet. When the powertrain control module applies electric current to the magnet, the central valve’s control piston slides, which moves the camphaser into the right position.

Depending on design, the central valve can also function as mounting bolt of the camshaft phasing unit. If this is the case, make sure not to use this valve again after it has been installed once, since it is designed as an expansion bolt.

INA is a system supplier and offers control valves, as well as central magnets and cam phasing units.

Benefits:

• Special filter on the valve protects it against failure from residual engine dirt
• Highest production accuracy ensure maximum operational precision
• Short transmission-medium distances (oil) deliver fast response
