Safety devices, so-called "devices with a safety function", are used for gas-side protection of the hydraulic accumulator against non-permitted excessive pressures and/or pressure increases resulting from non-permitted temperature increases.
In detail these are:
- Burst disk,
- temperature fuse and
- gas safety valve.
HYDAC safety devices have a CE marking and are shipped with a declaration of conformity.
A gas safety block simplifies the operation of hydraulic accumulators on the gas-side and also provides a means of attaching the above safety equipment using the various ports.
