Odd problem with PVG 32 valve

Odd problem with PVG 32 valve

Odd problem with PVG 32 valve

(OP)
I have an odd problem with some PVG-valves with a PVEH module.
With only 0,5  x UDC as a signal voltage, being in according with the documentation for the valve, this will normally positioned the main spool in neutral.  
But I have discovered some unintended travel of the spool, as again induce a motion of the component there are connected to the valve in this condition.
This failure is infrequent, but annoying.

Had anybody experienced anything like this?
