RE 50129-B/02.19, Accumulator shut-off block type ABZSS, 0532VAW, 

Bosch Rexroth AG

  

In case of line connections (hose or pipe) at inlets or outlets of the accumulator 
shut-off block, e.g. for connection of components, the relevant standards and 
country-specific rules are to be observed. When designing the line connection (hose 
or pipe), potential hydraulic and mechanical maximum loads and the necessary 
safety allowances for different operating conditions have to be observed. These have 
to be determined separately, e.g. positive or negative pressure peak. The operating 
and maintenance instructions of the components and line connections must also be 
observed.

It is imperative to provide for absolute cleanliness. The accumulator shut-off block 
and all other parts used must be installed free from dirt. 
Contamination of the hydraulic fluid may considerably reduce the life cycle of the 
accumulator shut-off block.

The used mounting screws have to comply with the dimensions and property classes 
specified in the data sheet of the respective accumulator shut-off block. Also the 
tightening torques specified in the data sheet of the respective accumulator shut-off 
block have to be complied with.

At accumulator shut-off blocks type ABZSS, the pressure relief valve cannot be 
replaced without destroying the sealing between pressure relief valve and 
accumulator shut-off block.

Bosch Rexroth recommends application of a sealing for assembly of a pressure 
relief valve at accumulator shut-off blocks type 0532VAW.

7.3  Prior to assembly

1. 

Before assembly of the accumulator shut-off block, check compliance of the type 
designation on the name plate with your order number.

If the material number of the  accumulator shut-off block does not match the 
number in the order confirmation, contact the Bosch Rexroth service for 
clarification. The address can be found in chapter 16.1 "List of addresses".

2. 

Observe the information on the maximum operating pressure on the name plate.

3. 

Check the scope of delivery for completeness and transport damage.

4. 

Make sure that all required seals are available and have been properly installed.
