Possible cause
Leaking connections
Retaining ring not
correctly inserted
Bonnet assembly
(top part) loose
Piston screw loose
Diaphragm damaged
Control element
(diaphragm, piston,
sealing element) defective
Foreign body jammed,
preventing tight closing
Impure function parts
Valve undersized
Valve is not dimensioned
for compressed air, and
therefore has no
compressed air
connection
Instruction manual
Troubleshooting
Check bonding or welding
and repair, if necessary
Check gaskets and
replace, if necessary
Position the retaining ring
so both projections of the
retaining ring lie in the
notches of the body
Retighten bonnet
assembly (top part)
Retighten piston screw
Replace diaphragm,
see Chapter 11
Replace cartridge.
Tense the spring, so the
valve opens and the
foreign body is flushed out
(caution: pressure
increase)
Clean pressure reducing
valve type 582, see
Chapter 11.2
Check valve dimensioning
(kvs value)
Remove compressed air
and select other valve
(e.g. pneumatic diaphragm
valve) for the application
