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.
