The Bosch Rexroth ABZSS 20 M-3X/210E/V12 (R901367388) is a high-quality hydraulic accumulator shutoff block designed to provide safety and control for hydraulic accumulator applications. This component is essential for the protection, isolation, and unloading of hydraulic accumulators, ensuring that they operate within safe parameters. The ABZSS 20 M-3X/210E/V12 is equipped with a pressure relief valve to guard against overpressure conditions, which is critical for maintaining system integrity and preventing potential damage. The pressure relief valve is specifically designed not to be used for control tasks; instead, its primary function is to offer protection by responding only when necessary.
The design of this accumulator shutoff block adheres to rigorous standards as outlined in the Pressure Equipment Directive of the European Union, highlighting its compliance with industry regulations. It features an accumulator adapter connection that facilitates a secure link between the shutoff block and the hydraulic accumulator. The Bosch Rexroth ABZSS 20 M-3X/210E/V12 has been crafted to work with a range of nominal diameters including DN6, DN10, DN13, and DN20, making it versatile for various system requirements. Its maximum operating pressure reaches up to series X bar levels, which allows it to handle demanding applications with ease.
This model's robust construction and precise engineering are indicative of Bosch Rexroth's commitment to quality in their hydraulic components. The ABZSS 20 M-3X/210E/V12 model is suitable for use in systems where reliable performance and safety are top priorities. With its specialized features and capabilities, this accumulator shutoff block represents a critical component in managing the effective use of hydraulic accumulators across diverse applications.

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.
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.

Notice:
Value pairs located in the areas of the characteristic curves with gray background cannot be realized with the safety valve. The characteristic curves shown here are only valid for a counter pressure of 0 bar in the discharge line.
1) Component series 1X, according to the Pressure Equipment Directive 2014/68/EU
Characteristic curves: Counter pressure in the discharge line
In principle, the valve should be operated without counter pressure in the discharge line, if possible. In case of counter pressure in the discharge line, the maximum possible flow is reduced. There is a relationship between maximum counter pressure pT in the discharge line and flow qV, which can be seen from the following characteristic curve. Characteristic curves for intermediate values of the response pressure which are not listed must be determined by means of interpolation.
When the flow approaches zero, the maximum counter pressure pT is in each case 10% of the response pressure. With increasing flow, the maximum counter pressure pT decreases.
Interpolation of intermediate values from the diagram
At the axis pT, mark 1/10 of the value of pA. Determine the next lower and the next higher characteristic curve for this point. The point marked at pT divides the section between lower and higher characteristic curve on the pT axis with a certain percentage. At the qVmax axis, divide the section between next lower and next higher characteristic curve in the same percentage as the section at the pT axis. From the zero position flow on the qVmax axis determined in that way, draw a straight line to the value on the pT axis marked before. Mark the system flow to be secured at the qVmax axis. Read off the maximum counter pressure for this value using the line at the pT axis drawn before.Characteristic curves: Counter pressure in the discharge line – size 6

qVmax Maximum flow in l/min
Area I Interpolation area I, for valves with pA = 30 … 110 bar and qVmax = 14 … 27 l/min
Area II Interpolation area II, for valves with pA = 115 … 400 bar and qVmax = 52 l/min
Determination of the maximum counter pressure
Example 1 (with already existing characteristic curve): Flow of the system/accumulator that has to be secured: qVmax = 15 l/min
Safety valve set to: pA = 315 bar.
From the diagram (see arrows, characteristic curve 7), read off the maximum counter pressure pT of approx. 22.5 bar.
Example 2 (with interpolated characteristic curve):
Flow of the system / accumulator to be secured: qVmax = 15 l/min
Safety valve set to: pA = 80 bar.
The value to be marked at the pT axis is calculated as follows: 1/10 x 80 bar = 8 bar.
From the diagram (see arrows, dashed characteristic curve), read off the maximum counter pressure pT of approx. 3 bar.

Safety instructions: Type-examination tested safety valves type DBDS 1)
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. 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. Fluid must not accumulate in the discharge system (see data sheet AD2000 A2).
Always observe application notes!
In the plant, the response pressure specified in the component marking is set at a flow of 2 l/min. The maximum 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! Basically, the requirements of the Pressure Equipment Directive and of data sheet AD 2000 A2 have to be observed! It is recommended to secure type-examination tested safety valves against inadmissible disassembly by means of wiring and sealing with the housing/block (bore available in the adjustment type).
Notice:
The system pressure increases by the counter pressure in the discharge line (port T) due to the increasing flow. (Observe the data sheet AD 2000 A 2, 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).
1) Component series 1X, according to the Pressure Equipment Directive 2014/68/EU
