Bosch Rexroth AG
Contact with salt water leads to increased corrosion on the valve. This can lead to
chemical corrosion of individual valve components.
Therefore, take suitable corrosion protection measures.
2.7 Notes on the valve use
▶
In case of bank assembly, only one solenoid of all valves may be energized
at a time.
▶
The valve must always be filled with hydraulic fluid.
▶
Be aware of possible pressure intensification if the valve is connected to the
chamber on the piston rod side of a differential cylinder. If the outflow of the
hydraulic fluid from this chamber is obstructed, pressure on the cylinder may
result in a pressure intensification that may damage cylinder chamber, supply
line, and valve.
▶
To ensure proper functioning, care must be taken that the pressure chamber of
the valve solenoid is always filled with hydraulic fluid.
▶
Switching off the valve solenoid results in a voltage peak due to the inductive
effect. The valve solenoid already contains an interference protection circuit
dampening this voltage peak. However, additional external switching measures
have to be taken, if required, to avoid an influence of the residual voltage peak on
connected electric circuits. The values for the residual voltage peak depend on
the valve solenoid used, see the
"Data sheet 29162-XE"
.
▶
The fuse may be accommodated in the related supply unit or must be separately
connected upstream.
The control electronics must comply with the requirements of the Explosion
Protection Directive 2014/34/EU.
2.8 Personal protective equipment
The machine end-user must provide the personal protective equipment (such as
gloves, working shoes, safety goggles, working clothes, etc...).
