Working Principle
Solenoids de-energized:
A port is exhausted,
connection from A port to R port.
Freely exhaust of A port,
P port is closed no pressure in A.
Solenoids energized:
Pilots are synchronously energized.
Connection from P port to A port.
Working pressure on A.
The R port is closed, no exhaust.
Malfunction:
Pilots non-synchronously energized.
Dynamic monitor of the failure.
A port exhausted connection from A port to R port,
low residual pressure on A. The pilot line has lost
the pressure on one side and is locked.
Dynamic inherently fail safe principle.
1 (P) = Air pressure port / 2 (A) = Power port (clutch / brake) / 3 (R) = Exhaust
Norgren-Herion XPs Safety valves comply with the Category IV of DIN EN ISO 13849-1, if the operating system has been designed and realised according to Category IV.

For external indication (e.g. visual, electrical or acoustic signal) of a malfunction,
the installation of a failure indication element is recommended. Such an element
is not necessary to fulfil the safety function of the valve. (For further information
please see the corresponding data sheet no. 5.14.420).
A suitable air treatment unit (dehydration, filtration, lubrication) must be
connected upstream of pressure port 1(P). Lubrication can only be omitted if the
connected consuming device and all additional equipment is suited for oil-free
operation.
Degree of filtration: 25 μm. The lubrication should be adjusted to supply only
enough oil to form a film on the valve spool and bore. Excessive lubrication may
cause a build-up of oil in the pilot lines and cause sluggish operation of the
valves.The size of pressure regulator, lubricator and filter must be consistent
with the inlet port size. An accumulator tank is recommended between the
pressure regulator and safety valve. The operating pressure must not drop
below 2 bar and the use of a pressure switch is suggested. Safety valves must be
installed as close as possible to the clutch and brake.
Caution: Non controllable elements such as quick exhaust valves, nozzles, non
return valves, etc. must not be mounted between safety valve and clutch brake.
It is the responsibility of the purchaser and/ or installer of the Norgren-Herion
safety valves to make sure that the valve and all other components comply
with all relevant national regulations and the specifications of the local safety
associations.
The valves should be checked at intervals depending on the loads to which they
are subjected, at least, however, once a year. The relevant tests must be carried
out according to the corresponding operation and maintenance instructions of
the unit and the local safety regulations.
In case of malfunctions the unit has to be tested and/or replaced immediately.
Repairs and maintenance must only be carried out by the after-sales service
of the valve manufacturer or by a qualified engineer trained by the valve
manufacturer. Important for use at presses: The combination with the electrical
press control must meet the DIN-EN-ISO 13849-1 requirements. If two separate
valves are used to control the clutch and brake, please observe data sheet no.
5.14.420.
All liability is denied for unauthorised modification of the units, installation or
usage not in accordance with the manual, the local safety requirements and the
principles of DIN-EN-ISO 13849-1.
Warning
These products are intended for use in industrial compressed
air and rail transport systems only. Do not use these products
where pressures and temperatures can exceed those listed under
‘Technical features’.
Before using these products with fluids other than those specified,
for non-industrial applications, life-support systems, or other
applications not within published specifications, consult NORGREN.
Through misuse, age, or malfunction, components used in
fluid power systems can fail in various modes.
06
The system designer is warned to consider the failure modes
of all component parts used in fluid power systems and to provide
adequate safeguards to prevent personal injury or damage to
equipment in the event of such failure.
System designers must provide a warning to end users in
the system instructional manual if protection against
a failure mode cannot be adequately provided.
System designers and end users are cautioned to review specific
warnings found in instruction sheets packed and shipped with
these products.
Our policy is one of continued research and development. We therefore reserve the right to amend,
without notice, the specifications given in this document.
