Remote electric, programmable signals to the amplifier controls all of the above functions.
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.

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
A single proportional solenoid valve can replace several conventional valves in a control system. Deceleration valve,
acceleration valve, flow controls and solenoid switching valve functions are all packaged in one proportional valve envelope.

Smaller manifolds and fewer hydraulic interconnecting lines are needed.

displacement (travel) and oil flow through the valve.
By controlling the rate of current increase or decrease,
the spool displacement or valve opening rate will increase or decrease resulting in acceleration
or deceleration control of the hydraulic actuator and its working load.
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
through the valve that exceeds levels traditionally experienced with on-off solenoid valves.
Smooth speed change transitions are obtained as compared to the high shock with on-off solenoid valves.
