18.20. 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.
Working with pressurised
pneumatic components poses a
risk of injury.
Prior to any work, disconnect
the equipment from the mains,
shut off the compressed air
supply, and vent all pressure in
the equipment to zero.
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.
