Possible cause
Operating voltage not present or insufficient;
Manual override knob not in neutral position;
Pressure supply insufficient or not present.
Pressure supply insufficient or not present;
Valves not in basic position (no power) during
pressure build-up;
Venting of exhaust aire channels insufficient
because silencers are too small or
contaminated (backpressure);
Contamination or foreign bodies in pilot or
main valve.
O-rings missing or pinched between the
modules;
profile seals missing or wrongly positioned
between valve and baseplate.
Remedy
Check the electrical connection.
Provide operating voltage acc. to
nameplate.
Turn knob to zero position.
Execute pressure supply with as large a
volume as possible (also for upstream
devices such as pressure controllers,
maintenance units, shut-off valves, etc.).
Minimum operating pressure ≥ ≥ ≥ ≥ ≥ 2,5 bar
Execute pressure supply with as large a
volume as possible (also for upstream
devices such as pressure controllers,
maintenance units, shut-off valves, etc.).
Minimum operating pressure ≥ ≥ ≥ ≥ ≥ 2,5 bar
Pressurize the valve block before the
valve switch!
Use matching, large-sized silencers or
expansion vessels.
Clean the contaminated silencers.
Pressurized the exhaust air channels in
pulses to blow out contamination; install a
new pilot or main valve if these measures
bring no result.
Determine the point of leakage or missing
seals.
Insert missing seals or replace damaged
seals.
