Safety pressure relief valves
direct, screw-in, conforming to PED Directive 2014/68/EU - certified by
CART /PED
Safety pressure relief valves, certified by
DEKRA according to Pressure Equipment
Directive 2014/68/EU (PED).
They are designed to operate as safety
components, limiting the maximum system
pressure or to protect parts of the
hydraulic circuit and accumulators from
overpressure.
The valves are factory set at the pressure
level required by the costumer, see
section
6.
The pressure adjustment screw is
protected with a lead sealed plastic cap to
avoid any tampering.
The screw-in execution is specifically
designed to reduce the dimension of
blocks and manifolds, without penalizing
the functional characteristics.

Notes:
1) The valves can operate only in the white area of the above diagrams.
The max admissible flow values within the white area are those for which the pressure increase remains within +10% with respect to the factory
pressure setting.
Pressure / flow values located in gray areas cannot be performed.
Before ordering the valve, check that the maximum admissible flow at the required pressure setting, is greater than the maximum flow
rate of the system or the accumulator to be protected.
2) The working range in above diagrams is valid without counterpressure in T line.
The factory pressure setting is increased by the counterpressure valve in T line.
As general rule PED valves should be operated without counter pressure in the T line.
In case of counter pressure in T line, the maximum admissible flow has to be reduced with respect to the values reported in the diagram, so
as not to exceed the limit of +10% with respect to the factory pressure setting. Contact Atos technical office for details.
