Error table
not working
Possible cause:
The control voltage must be
>90% of its nominal value.
Remedy:
Measure the control voltage directly in
front of the solenoid. If the operating voltage is
lower or a long cable is used, a heavier conductor
must be chosen to keep the voltage drop small.
possible cause:
Solenoid coil defective,
no continuity
Remedy:
Replace solenoid
impaired function
Possible cause:
Diaphragm soiled
Remedy:
Control bore in the diaphragm
Possible cause:
Core jammed
Remedy:
Clean core and core tube
Possible cause:
Valve seat leaking
Remedy:
Clean control bores
inadmissible operating conditions
Possible cause:
Operating pressure excessive
Remedy:
Check maximum operating pressure and
reduce pressure accordingly.

Directives and certificates
Note to Pressure Equipment Directive (PED)
The valves of series 84070 and 84080 corres-
pond to Article 4 § 3 of the Pressure Equip-
ment Directive
2014/68/EU
(PED). This means
that these valves are designed and manufactu-
red in line to the good engineering practice.
The CE-sign at the valve refers not to the
PED. Thus the declaration of conformity is not
longer applicable for this directive.
Notes on EEC Directive
The valves shall be provided with an elec-
trical circuit which ensures the limits of the
harmonized standards EN 61000-6-3 and
EN 61000-6-1 are observed, and hence the
requirements of the Electromagnetic Compa-
tibility Guideline
2014/30/EU
satisfied. The
CE-marking is related to this EU-requirements.
NSF certificate
A2
This valve is tested and certified
as a component by NSF International
against NSF/ANSI Standard 42
for materials and structural
integrity requirements only.
