Function testing insures the correct dynamic manual and electrical operation of the PVG 16 and PVG 32
valve assembly. This test should be performed after completing the pressure adjustments. Each section of
the assembly must be tested:
1. With the pump connected, remove the plugs from the section to be tested as described in the
Pressure setting after assembly
the cylinder and the "B" port to the base end of the cylinder (see the figure below).
Inlet Pressure Measurement
30 to 350 bar
[435 to 5075 psi]
PC Pump 14 l/min
[3.4 US gal/min]
2. Shift the control lever of the tested section towards the valve and observe cylinder retraction. Shift
the same control lever away from the valve and observe cylinder extension. Repeat several times. On
valve groups with PVM's on the "B" side, the cylinder movement will be opposite when shifting the
handle in the same direction.
3. Check the spool travel smoothness in both directions.
