LR3/Disco 3
PCV Non-controlled (A)
The ball valve (3) will only be operated through the force exerted upon it by the spring (4). Thereby, the PCV is classed as
open.
PCV Controlled (B)
The current flowing through the solenoid (6) draws the pin (7) down. This in turn transfers the magnetic force via the pin to
the ball valve (3). The pull of the pin, and the pressure on the ball valve, is proportional to the valve flow (9).
