The above diagram shows the valve application, meeting the requirements of Directive 2014/68/EU and ISO 4126-1 for a maximum short-term
pressure surge in the circuit 10 % higher than the set cracking pressure when opening the valve.
The dynamics of the valves depend on the kinematic viscosity of working fluid.
Measurement conditions: oil Renolin VG 32, T = 40 °C (104 °F), V = 0.5 l (0.132 gal US)

The valve meets the relevant requirements of legal regulations and standards as amended:
Directive 2014/68/EU (harmonized NV ČR 219/2016) Pressure equipment
ČSN EN ISO 4413 - Hydraulics – general rules and safety requirements for hydraulic systems and their components
ČSN EN ISO 4126-1 Safety devices for protection against excessive pressure / Part 1: Relief valve
Other regulations and standards used:
ČSN ISO 6403 Hydrostatic drives. Valves for flow and pressure control. Test methods
ČSN EN ISO 9001 Quality management systems
ČSN EN ISO 12100 Machinery safety / risk analysis
Directive 2006/42/EU about machinery / chapters used: 1.7.4 Instructions for use, appendix III CE marking
ČSN EN 82079-1 Preparation of instructions for use – Structuring, content and presentation / Part 1: General principles and detailed requirements
3.7 Legislation and standards:
An overview of all possible valve modifications as described in the order key.
Pressure level
is determined by the stiffness of the spring used and the parts used during assembly. It cannot be changed by the user.
Sealing material
the user cannot change this as part of the seal is inside the valve.
The user must not disassemble the valve.
Valves are set by the manufacturer ARGO-HYTOS
The valves are set to the required cracking pressure at a given flow rate and are sealed by the manufacturer. The set pressure in bar and flow in I/min
are given in the valve description. The seal contains the ARGO-HYTOS logo. The customer must not change the valve settings or break the seal.
Valves set by the user
The valves are tested by the manufacturer and the adjusting screw is completely loosened (set pressure p = 0 bar). The valves are not sealed, and the
set pressure and flow rates are not filled in the valve description – VPP2-06-xV/xx-CE1017. The user assumes the responsibility for setting both the
cracking pressure and sealing the settings.
Setting the required valve pressure:
› turning adjusting screw to the right = higher cracking pressure
› turning adjusting screw to the left = lower cracking pressure
