Function

The accumulator shut-off block serves for the protection, isolation and unloading of hydraulic accumulators. It is classified based on its use according to the Pressure Equipment Directive 2014/68/EU article 4, section 3.

 

The connection between the accumulator shut-off block and the accumulator is realized by means of an accumulator adapter. An optional, additional, electrically operated 2-way valve (normally open) enables automatic unloading of the accumulator in case of shutdown or "emergency off function". The accumulator is protected from inadmissible overpressure by means of the pressure relief valve.

 

The pressure relief valve must not be used for any control tasks. Sufficient difference between the pressure set at the pressure relief valve and the operating pressure must be ensured. Response of the pressure relief valve should be prevented.

Type-examination tested safety valves type 0532VA according to Pressure Equipment Directive 2014/68/EU

Before ordering a type-examination tested safety valve, it must be observed that for the desired response pressure p, the maximum admissible flow qVmax of the safety valve must be larger than the maximum possible flow of the system/accumulator to be secured. In this respect, the applicable regulations must be observed! According to the Pressure Equipment Directive 2014/68/EU, the increase in the system pressure due to the flow must not exceed 10 % of the set response pressure (see component marking). The maximum admissible flow qVmax stated in the component marking must not be exceeded. Discharge lines of safety valves must end in a risk-free manner. Accumulation of fluids in the discharge system must not be possible (see AD2000 - data sheet A2).

 

Always observe application notes!

The response pressure specified in the component marking is set in the plant. The maximum admissible flow stated in the component marking applies for applications without counter pressure in the discharge line (port T). By removing the lead seal at the safety valve, the approval according to the Pressure Equipment Directive becomes void! The requirements of the Pressure Equipment Directive and of data sheet AD2000 A2 must be generally observed! It is recommended to secure type-examination tested safety valves against inadmissible removal from the screw-in housing/block by means of wiring and sealing with the housing/block (bore available in the adjustment element).

 

Notice:

The system pressure increases by the counter pressure in the discharge line (port T) due to the increasing flow. (Observe the data sheet AD2000 A2, point 6.3!) To ensure that this increase in system pressure caused by the flow does not exceed the value of 10% of the set response pressure, the admissible flow has to be reduced dependent on the counter pressure in the discharge line (port T) (see diagrams/characteristic curves).
