Normal operation of the system does not require any valve manipulation.
The valve automatically limits the maximum value the pressure in the circuit and protects it against pressure overload.
6.4 Normal operation
DO NOT EXCEED THE MAXIMUM PARAMETERS,
listed in table 3.3.
OBSERVE OPERATING RESTRICTIONS AND AVOID RISKS,
referred to in paragraph 2.
USE PROTECTIVE EQUIPMENT
When working with hydraulic fluid, we recommend using safety goggles, protective rubber gloves and safety shoes with non-slip soles.
In the event of a system power failure the valve remains set.
Based on the results of the risk analysis, two potential defects were identified:
› External leakage of the valve due to seal damage associated with leakage of working fluid
› Loss of valve function usually manifested as a drop in system pressure.
6.5 Extraordinary and emergency situations
CAUTION
Switching off the pressure source and relieving the circuit
In the event of an emergency, switch the power source off (pump) and relieve all parts of the hydraulic circuit,
including the hydraulic accumulators, by connecting them to the tank. Before any work on the circuit, such as
removing a valve ensure that the circuit is depressurized. Otherwise there is a risk of leakage of the working
fluid and contamination of personnel.
Defective valves must be replaced / repaired. Before disassembly, clean and degrease the hexagon size 32 on the valve body.
This will prevent the wrench from slipping when loosening the valve and avoid possible injury.
The valve is released with a size 32 wrench by turning it counter clockwise.
ENVIRONMENTAL PROTECTION
Spilled working fluid must be removed immediately, eg with suitable absorbents, contaminated objects in the vicinity must be
cleaned or disposed of. Contaminated objects and residues of leaked working fluid must be disposed of in accordance with the
applicable environmental regulations.
FIRST AID
In the event of personal contamination, the contaminated clothing must be removed immediately, the skin washed thoroughly with
soap, or treated with a suitable cream.
In the case of contact with eyes, rinse immediately with clean water and seek medical attention. Also see medical advice if the
working fluid is accidentally swallowed or in the event of an allergic skin reaction.
Repairs to a defective valve are performer only by the manufacturer. Remove residual working fluid from the now removed defective valve and pack
it to prevent mechanical damage and outer contamination of the package during transport. Send the packaged valve with a description of the defect
to the customer’s address.
The user is only entitled to replace the external valve seals, which are supplied as a set of spare parts.
The manufacturer provides a 1-year warranty for the new valve. However, the right to make a complaint may not be accepted by the manufacturer if
the valve is mechanically damaged, the sealing material is damaged by an aggressive liquid or if incorrect use of the valve, not in accordance with
these operating instructions has been proven.
