Intended use
The SV01/SV03/SV05 series of double valves are safety components designed and
manufactured in accordance with Machinery Directive 2006/42/EC and bear the CE
mark. The safety function of the safety valve is to shut off the supply of
pneumatic energy and to exhaust any pneumatic energy from downstream of the
valve. The safety function of the 5/2 safety valve is to at least stop the
actuator (one channel of the double valve stuck in a worst-case position)
respectively to return the actuator to its home “safe” position when the valve
operates fault free. The SV01/SV03/SV05 series of double valves are redundant
3/2 or 5/2 valves that are designed to meet the aforementioned safety
functions. Typically, these valves are implemented to meet the Category 4
and/or Performance Level e requirements of a machine’s (or system’s) safety
circuit as determined by a risk assessment of the hazards and tasks required
of employees that interact with the machine/system.
▶ See chapter 12 “Technical Data” for the standards and test values complied
with and adhered to by the product. See the declaration of conformity for
product-relevant EU directives.
The 3/2 safety valve is designed to supply air to a zone or entire
machine/system until signaled to shut off and exhaust residual downstream
pneumatic energy from the machine. Thus, reducing the hazards associated with
the presence of residual energy during employee access and/or minor servicing.
The safety function of the 3/2 safety valve is to shut off the supply of
pneumatic energy and to exhaust any pneumatic energy from downstream of the
valve.
NOTE: The safety valve cannot exhaust pneumatic energy from downstream of
obstructions such as check valves and closed center function valves. The 5/2
safety valve is designed to control the direction of airflow into and out of a
double-acting cylinder or another pneumatic actuator in order to drive the
cylinder forward or backward to suit the requirements of the machine
operation.
The safety valves are designed for external monitoring for the safe, redundant
operation of the valves. The safety valves are constructed of redundant, 3/2
or 5/2 spool type valves, and have an overall function of a single solenoid
pilot-operated, spring return valve. Every single valve in the safety valve is
equipped with a PNP proximity sensor. Monitoring both of these sensors on
each actuation and de-actuation of the safety valve provides a diagnostic
coverage of up to 99%. Monitoring of these sensors is to be done by an
external monitoring system.
Safety Function According to ISO 13849
The safety valves are designed in accordance with the requirements listed in
ISO 13849-1 and -2. The safety function of the 3/2 safety valve is not only to
supply compressed air (pneumatic energy) to the machine/system when the two
valve elements are actuated simultaneously but also to shut off the supply and
to exhaust any downstream compressed air when both valves are switched off. A
fault in the system where only one valve actuates when switching on or only
one deactivates when switching off prevents air from being supplied downstream
and simultaneously exhausts any air that is already downstream. Monitoring of
the two proximity sensors by the user’s external safety monitoring system
makes it possible to detect these fault situations and to shut off and prevent
further electrical energization of the solenoids.
The safety function of the 5/2 safety valve is to drive a double-acting
cylinder or another pneumatic actuator forward when the two valve elements are
actuated simultaneously and to drive the cylinder or other actuator back to
its home “safe” position when both valve elements are switched off. A fault in
the system where only one valve actuates when switching on or only one
deactivates when switching off causes the safety valve to supply air to port 2
of the valve and to simultaneously open port 4 to exhaust (port 5). This, in
turn, causes the cylinder or other actuator to return to its home “safe”
position. Monitoring of the two proximity sensors by the user’s external
safety monitoring system makes it possible to detect these fault situations
and to shut off and prevent further electrical energization of the solenoids.
The control outputs of the safety system must be designed and constructed to
meet the Category and/or Performance Level requirements of the safety system,
as determined by the risk assessment of the machine. Normally, the output to
the solenoids is a dual-channel output from a safety relay or safety PLC.
Common Cause Failure – CCF
The product has been engineered and manufactured according to the basic and
well-tried safety principles of ISO 1389-1 and -2.
Critical failure modes and causes:
▶ Incomplete reversal – caused by the incomplete return of solenoid valve B.
▶ The pressure applied at port 4 is not being dissipated – caused by the
incomplete return of solenoid valve A.
▶ Failure of the safety function – caused by the simultaneous incomplete
return of both solenoid valves (A and B).
Common Cause Failures (CCF) are failures of different components, resulting
from a single event.
CCF is not to be confused with cascading faults or common mode faults. Common
cause failures can cause loss of the safety function, especially in dual
channel circuits where both channels could fail simultaneously due to a single
event. The following measures ensure that failures due to common causes are
avoided:
▶ Maintain compressed air quality, i.e., filtration, pressure regulation, and
lubrication.
▶ Avoid compressor oils that can cause valve seals to swell, soften, or
otherwise deteriorate.
▶ Operate within prescribed temperature limits.
▶ Install the valve such that the normal stroke travel of the valve element
is perpendicular
to the main direction of machine vibration and/or mechanical shock.
▶ Observe the permissible values for vibration and shock stress.
▶ Do not use a test pulse longer than typically 400 to 600 ms and a pulse
width of 0.4 ms to 0.8 ms.
▶ Avoid external magnetic fields.
▶ Do not plug the valve exhaust port.
▶ The silencer is included in the scope of delivery. Make sure that the
silencer is not clogged, otherwise, the silencer must be replaced (see chapter
11 „Spare Parts“).
Diagnostic Coverage
A diagnostic coverage of 99% is achievable through appropriate integration of
the safety valve into the safety control system. The monitoring system must
check for the proper change of state of each valve sensor (S1 & S2) with each
change of state of the safety control system output to the valve solenoids
(Sol 1 & Sol 2). Detection of a fault by the safety control system must
trigger a shut-off of the safety controller’s outputs to the valve solenoids
(Sol 1 & Sol 2). See “Test Procedure”.
NOTE: On 5/2 versions, in the event of a fault where the side A valve
element is deactivated and the side B valve element sticks within a very
small, specific range of its travel, there is a possibility of a condition
where the pressure may not be present in port 2. This fault is detectable
because one position sensor’s output will be high (on) and the other sensor’s
output will be low (off).
WARNING: On 5/2 versions, in the event of loss of pressure in port 2
during a fault could cause unexpected movement of a cylinder that is being
controlled by the valve.
Fault Modes
Note that normal operation requires that Sol 1 & Sol 2 be energized
simultaneously for switching the safety valve on, and de-energizing both Sol 1
and Sol 2 simultaneously for switching the safety valve off. Faults that could
occur during normal operation:
Sol 1 & Sol 2 energized simultaneously
▶ S1 ON, S2 OFF
▶ S1 OFF, S2 ON
▶ S1 OFF, S2 OFF
Sol 1 & Sol 2 de-energized simultaneously
▶ S1 ON, S2 OFF
▶ S1 OFF, S2 ON
▶ S1 ON, S2 ON Misuse

the sensors. This malfunction could happen for a variety of reasons, such as:
▶ Defective piston seals,
▶ Main valve elements experiencing a switching delay due to dirt or resinous
oil,
▶ Insufficient electrical signals to valve solenoids; suitable voltage not
available,
▶ Receipt of signals at solenoids not synchronous,
▶ Pilot valves experiencing a switching delay due to damaged components, dirt,
or resinous oil,
▶ Excessive water build-up in the valve.
Care and Maintenance
Care
NOTICE
Damage to the product due to the use of solvents and aggressive cleaning
agents!
The product can be damaged if washed with a solvent or aggressive cleaning
agent. The chemical resistance of the valve material to such products is not
guaranteed. Solvents and aggressive detergents will destroy the surface,
labeling, and seals of the product.
▶ Make sure that no solvents and aggressive cleaning agents come into contact
with the valve.
Damage to the product due to washing at high pressures and temperatures!
The product will be damaged if you clean it with high pressure and/or at a
high temperature.
▶ Make sure that the product is not cleaned with high pressure and/or at a
high temperature.
No special care is required for the safety valve. Note the following if you
would like to clean the valve:
▶ Check that all seals and plugs for the plug connections are firmly seated so
that no humidity can penetrate the safety valve during cleaning.
▶ Only clean the safety valve using a slightly damp cloth. Only use water to
do this and, if necessary, a mild detergent.
Maintenance
WARNING
Risk of injury while working on a running system!
Working while the system is running can cause major injuries from moving
machinery.
▶ Bring the system mode into a state in which working movements are no longer
possible.
Wait until all moving machine parts come to a standstill, and protect the
system against being switched on.
In normal operation, the safety valve is maintenance-free. However, to ensure
the correct function, the safety valve must be actuated at least once per
month.
▶ Activate the safety valve at least once per month.
▶ Perform a functional test at least annually (see “Test Procedure”)
The safety valve seals may age faster in aggressive ambient conditions. A
damaged seal can be recognized by parts of the seal visibly protruding from
the housing gaps. Defective seals will lead to pneumatic leaks. Please return
to the factory in case of a faulty product.
▶ Regularly check that the seals are in perfect order.
▶ Immediately exchange the safety valve if the seals are defective.
▶ Check regularly whether all plug connectors are firmly fitted.
▶ Establish the maintenance intervals according to your ambient conditions and
enter them in the system-dependent maintenance plan.
▶ Observe the system-specific maintenance intervals.
In case of any maintenance requirements, it is advisable to replace the entire
safety valve as this is the only way of ensuring a life cycle value for the
entire valve.
The operator is responsible for determining the maintenance intervals.
