Stroke rate
The stroke rate is dependent on the minimum flow
opening, the volume of oil and the working and return
pressures. The connecting openings allow a working
stroke rate of up to 0.8 m/s. Although this is limited by
the extent to which the system heats up due to the
high stroke rates. The system temperature should not
exceed 60 °C.
Safety instructions
If the layout of the system gives the Force Cylinder an
excessive displacement volume due to excess over-
travel and/or seizing of the cylinder, the pressure in the
system can exceed the admissible value of 280 bar. In
critical situations, this effect will be counteracted by
the opening of a rupture valve at 517 bar.
The couplings are designed for a nominal pressure of
300 bar and 1000 bar rupture pressure.
On the gas side, the Accumulator is pressurised at 150
bar and is subject to Pressure Equipment Directive
97/23/EC.
To monitor safety during the process, we recommend
installing a control fitting as an additional check on the
gas side - see range of accessories.

Comments
The Accumulator and the Force Cylinder are pressure
vessels and as such are subject to the Pressure Equip-
ment Directive 97/23/EC.
During cutting and hole punching operations the nomi-
nal force of the Compact Cam should only be utilised
up to 75% to minimise impact during cutting which is
reinforced by the Accumulator. Impact during cutting
can be reduced by polished tool edges (e.g. roof
shape) and so downtime can be reduced.
