2 Basic safety notes
2.1 Intended use
The pressure maintenance valve was designed for installation in a
machine to temporarily prevent the venting of the pneumatic
consumer 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
application parameters Technical data [}9].
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.
2.2 Ambient conditions and operating conditions
Required ambient conditions and operating conditions
Incorrect ambient and operating conditions can make the product
unsafe, leading to the risk of serious injuries, considerable material
damage and/or a significant reduction to the product's life span.
• Make sure that the product is used only in the context of its
defined application parameters, Technical data [}9].
• Make sure that the product is 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
environments.

the manufacturer
Due to its technical training, knowledge and experience, service
personnel of the manufacturer is able to perform the delegated
tasks and to recognize and avoid possible dangers.
2.5 Notes on particular risks
The general rule is:
• The pressure maintenance valve temporarily prevents the
venting of the pneumatic module if there is a loss of air
pressure in the supply line. For this reason it is always assumed
that residual energy is stored in the system.
• Therefore the product must be ventilated before carrying out
any assembly, conversion, maintenance or adjustment work.
Here, it must be checked which module and which function is
triggered by this -> It is necessary to ensure that no person can
be harmed.
• For all work, secure the product against accidental operation.
• Any hazards that arise for downstream consumers must be
identified separately and protected against by the operator
• Only qualified personnel may disassemble the product.
• Perform maintenance, modifications, and additions outside the
danger zone.

4 Description
The SDV-P consists of two check valves connected in parallel,
which open when pressure is applied and reciprocal vent the
return direction.
At a pressure failure of the supply line, the check valves close and
prevent a pressure drop.
