Basic safety notes
Intended use
The pressure maintenance valve was designed for installation in a
machine to temporarily prevent the venting of the pneumatic con-
sumer through the valve at a pressure failure of the supply line.
Thus, a temporary force- or position maintenance can be realized
at different actuators. Especially suited fo grippers, which can not
be equipped with a mechanical gripping force maintenance.
The product is intended for installation in a machine/system. The
requirements of the applicable guidelines must be observed and
complied with.
The product may be used only in the context of its defined applica-
tion parameters (5, Page 8).
The product is designed for industrial use.
To use this unit as intended, it is also essential to observe the
technical data and installation and operation notes in this manual
and to comply with the maintenance intervals.
Ambient conditions and operating conditions
•Make sure that the product has a sufficient size for the application.
•Make sure that the environment is free from splash water and
vapors as well as from abrasion or processing dust. Exceptions
are products that are designed especially for contaminated en-
vironments.

Notes on particular risks
Generally valid
•In failure of the supply line, the pressure maintenance valve
prevents temporarily the venting of the pneumatic consumers
through the valve.Therefore it must always be assumed that
there is residual energy stored in the system.
•Before installation, modification, maintenance and adjustment,
the module must be vented.Here it is necessary to determine
which consumers and which function is triggered so -> It must
be ensured that no person can be injured.
•For all work, secure the unit against accidental operation.
•Dangers emanating from the downstream consumers, must be
separately registered and safeguarded by the operator.
•Only specially trained staff should disassemble the module.
•Perform maintenance, modifications, and additions outside the
danger zone.

Air connection
NOTICE
Observe the requirements for the air supply
(5, Page 8).
WARNING
Risk of injury during connection!
•Switch off the energy supply.
WARNING
Risk of injury, when removing the air hoses!
•The air hoses at the outputs must be removed carefully , be-
cause they are under pressure even after switching off the
power supply.
Fig. 2 Air connection
Two check valves connected in parallel, each of which opens au-
tomatically the reverse flow direction when a pressure is applied
and thus closes the pressure line.
