This document describes how to set up

the Vickers 30 design proportional valve

power amplifiers.

The Eurocard type amplifiers covered in

this procedure are listed below. More

detailed information on the power

amplifiers can be found in Vickers

catalog GB-C-2007C.

AMPLIFIER VALVE

EEA-PAC-2007C for more detailed

information on these power amplifiers.

This is an easy-to-use procedure for

anyone with a little understanding of

how proportional valves work.

Proportional valve solenoids are current

controlled. This current is usually

regulated by varying the command

voltage into the amplifier. The greater

the current to the solenoid coil, the

greater will be the valve spool

This document does not deal with valve

sizing. However, it should be recognized

that proper sizing will directly affect the

control of acceleration and deceleration.

Select the smallest valve size possible

and the smallest spool size within that

valve size. This results in pressure drop
