5. Target group of users
All the activities relate to the valve, especially the installation and adjustment of cracking pressure, require technical expertise and experience in the
field of hydraulics. The minimum required level of professional competence is CETOP level 2. This level is generally defined as the performance of
various activities that require an understanding of technical factors and contexts. This may lead to the need of correct interpretation (e.g. tolerances,
operating methods) or to the application of various non-repetitive procedures. This may require the performance of instructions, simple analyses and
diagnostics, the ability to respond operationally to changes. Teamwork is often necessary.
It is forbidden for the following to carry out any activities related to this product:
› Minors (the exception being practical training of students under the professional supervision of a teacher)
› Without the specified professional competence
› Under the influence of alcohol and/or drugs
› Patients whose health condition could affect safety (reduced attention span and ability to react in a timely manner, excessive fatigue)
› Under the influence of drugs that have a demonstratable effect on attention and the ability to react in a timely manner
› Those with an allergy to hydraulic working fluids
6. Instructions for use broken down into product life stages
The valve is standardly packed in vacuum-shrinkable PE foil and protected against moisture and dust. An identification label is affixed to the
packaging. Products should be stored for the necessary time at a temperature of 0 ... +30 °C (32 ... +86 °F) in a dry environment with a relative
humidity of up to 65 %.
After a longer period of storage, we recommend checking the product for damage caused by corrosion, replacing the external seals and flushing
the product with clean oil before connecting it to the hydraulic circuit.
6.1 Transport and storage of product
Check that the valve type corresponds to the identification plate.
Cut the package carefully with scissors and carefully remove the valve from the package.
Unpack the valve in a clean environment and avoid contamination of the valve.
The packaging is made of PE and can easily be contaminated with residual oil from the valve.
Dispose of the packaging in accordance with the applicable environmental regulations.
6.2 Product installation
CAUTION
Slippery valve surface
The valve contains a small amount of residual oil after the hydraulic function test performed by the manufactu-
rer. A slippery valve surface can lead to dropping when handling, causing minor injury or damage to the valve.
The valve is designed to be mounted into a
B2 cavity
with connection thread 7/8-14 UNF. Chamber B2 complies with ISO/TR 17209. The valve can
also be mounted into a VC10-2 Hydraforce or C-10-2 Eaton cavity. The mounting position of the valve is arbitrary.
Before mounting, check the valve surface and seals for damage. Inspect the cavity that it is clean, deburred and undamaged. We recommend
lubricating the valve thread and the sealing rings with a suitable grease for easier installation. Insert the valve into the cavity and turn the valve
clockwise (right-hand thread) to screw the valve into the cavity. Tighten the valve with a torque wrench size 27 to 50 + 5 Nm. Excessive resistance of
the valve when screwing in indicates a tight cavity. In this case, unscrew the valve by turning it counterclockwise and check and calibrate
the cavity.
CAUTION
Tight / non-conforming valve cavity
Never mount the valve using excessive tightening torque. The valve will be deformed, unreliable or completely
lose function.
