17.22. Pressure relief valve
The pressure relief valve automatically begins to vent air from the system if the pressure in the
compressed air circuit exceeds its pre-set value. The pressure relief valve closes as the pressure
drops.
The pressure in the compressed air circuit can only increase because of an
increase in flow resistance in the compressed air lines or as a result of a dryer
malfunction (e.g. solenoid valve malfunction), and therefore the repeated
opening of the relief valve requires a dryer function check and repairs if
necessary!
Consultation with the manufacturer is required before any adjustment is made to
the relief valve!
The outlet openings on the relief valve may not be blocked and the egress of
compressed air through them may not be restricted.
