Accumulator shut-off block - Type ABZSS

Consultation request
Type code

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. 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 maximum operating pressure and the working pressure must be ensured. Response of the pressure relief valve should be prevented, if possible.
