CAUTION
Danger of displacement of the adjusting Bolt on the pilot valve (AS) during tightening of the locking nut!
Potential unintended change of the nominal pressure.
► Always fix the the adjusting screw on the pilot valve (AS) during tightening of the locking nut.
► Check the nominal pressure of pressure gauge KH5 after tightening the locking nut.

ADJUSTING THE SPEED CONTROL
Turning the Speed Control Valve clockwise will increase valve response time. Turning the
Speed Control Valve anti-clockwise will improve valve stability
. Only if instability is observed
should the Speed Control Valve be set to a value other than in the table.
a. It is recommended the speed control valve is adjusted after valve has run for at least 10
minutes. This allows air in the system to purge.
b. If instability occurs, move the valve one notch anticlockwise to a lower setting and wait 1
minute.
c. Repeat step b if instability is still present.
