Does anyone have a data sheet or wiring diagram for this product.
I'd estimate that it must be 20 years old approximately.
It functions mechanically, the wiring simply needs to be replaced.
during the disassembly of the wiring harness, I discovered that the VDSP 20D29 is fully mechanical.
It includes a bracket for a position switch in order to supply power to the motor, however, the valve itself has no electrical components.
A spec sheet would be very interesting if someone has one.
VDSP20 was transferred to Parker Germany in 1980. This was available with 1 to 3 spools. It was rated to 10 GPM and 3000PSI. Parker Germany (in Cologne at the time) sold the rights to Log Hydraulic in West German, which is now Weber Hyd.
