The Bosch Rexroth ABZSS 30 M-3X/330E/S630V12-104 (R901424462) is a high-quality hydraulic accumulator shutoff block designed for efficient and secure operation in hydraulic systems. This component acts as a safeguard for hydraulic accumulators, providing isolation, protection, and unloading capabilities. It is compliant with the Pressure Equipment Directive of the EU, ensuring it meets stringent safety and performance standards. The device features a robust connection to the hydraulic accumulator via an accumulator adapter, ensuring a reliable link for optimal functionality. The inclusion of a pressure relief valve serves as a critical safety measure, protecting against excessive overpressure conditions that could otherwise compromise system integrity. However, it's important to note that this pressure relief valve is not intended for control tasks; its sole purpose is to offer protection. For optimal performance, users must maintain an adequate margin between the maximum operating pressure and the working pressure of their system to avoid unnecessary activation of the pressure relief valve. The ABZSS 30 M-3X/330E/S630V12-104 comes in various nominal diameters including DN6, DN10, DN13, and DN20 to accommodate different system requirements and is part of component series X which signifies its design iteration. It can withstand a maximum operating pressure that ensures it can be integrated into a wide range of high-pressure applications without compromising on reliability or safety.

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.

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.
