To assure delivery of the proper Controller, Form No)
6013, pages 6 and 7, (or a facsimile) must be
completed. Instructions for completing the forms are
shown on page 7.
The following is a chart specifying the recommended
pressure control ranges for the HCJ, HCS or HCF
Hydraulic Controllers when used with Gresen directional
control valves with hydraulic remote spool actuators.
Model V20 Control Valve .....
.55-255 PSI [3,8-17,6bar]
Model V42 Control Valve .....
.25-145 PSI [1,7-10,0 bar]
Model V70 Control Valve .....
.25-225 PSI [1,7-15,5 bar]
If other directional control valve applications are
encountered, contact the factory
The following pressure control ranges (spring range) are
Spring Part NO.
0-120 PSI [0-8,3 bar]
0-200 PSI [0-13,8 bar]
0-250 PSI [0-17,3 bar]
0-300 PSI [0-20,7 bar]
0-400 PSI [0-27.6 bar]
When specifying a pressure control range, always
specify the start pressure in the range. The start
pressure must be added to the spring range (Example:
A 0-200 PSI range spring with a start pressure of 55 PSI
should be specified as "55-255 PSI".) The start pressure
is shim adjustable and increases the pressure from 0
PSI to the desired start pressure: for instance, 55 PSI at
a 4° handle stroke. This start pressure allows the valve
spool to shift past the neutral deadband of the spool
travel and start into the metering portion of the spool
travel at the first 4° of handle movement.
