CAT 330D-L

Thanks STVO!

Yes, when the model doesn't move the pressure drop to a minimum level roughly from 1 to 6 Bar depending from the flow supplied by the pump at the minimum RPM. The less the flow, the less the residual pressure when the center is open.
And if someone need it for some reason, the valve can be changed in close center simply avoiding to drill a hole in the aluminium head of the distributor.

Now i am ready for selling.

See you....
