Troubleshooting
Pressure control valve engages compressor for idle stroke when pressure is below
0.77...0.80 MPa, and for operating stroke when pressure is below 0.65 MPa and over
0.70 MPa
Dirt accumulation in cavities and
channels of pressure control valve
Rinse and clear pressure control valve
Faulty location of pressure control
valve adjusting cap
Adjust pressure control valve as specified in sub-
section 3.9.5 “Check and adjustment of pneumatic
system pressure control valve”
Damaged rubber parts of pressure
control valve, spring shrinkage
Replace damaged parts or send them to repair
workshop
Tilting, deadlock of spool of adjust-
ing part of pressure control valve
Ensure freedom of the spool movement, lubricate it
or refer pressure control valve to repair workshop
Pressure control valve gets actuated frequently (engages pneumatic com-
pressor) without air bleeding from receiver tank
Air leakage from pneumatic sys-
tem or pressure control valve, fail-
ure of back-pressure valve
Detect and stop the air leakages
Pressure control valve operates in mode of pressure-relief valve
Pressure control valve adjusting
cap is turned for too much
Adjust pressure control valve as specified in sub-
section 3.9.5 “Check and adjustment of pneumatic
system pressure control valve”
