The piston cylinder system is the heart of the pressure balance and the key to its performance and
hydraulic operation. Add pressure capability for your existing pressure balance by adding piston/
cylinder(s). This cost-effective Minerva piston cylinder fits in many pressure balances!
There are 5 different sizes of Minerva piston cylinders in diameter ranges between 2.3 - 10 mm.
The benefit is that you can select the one which is best for your desired pressure range and further requirements.
The small diameters give a high pressure to mass reducing excessive amounts of masses and related labour and keeps the total system as compact as possible.

Minerva piston cylinders are available in two versions:
MNR 520-PCxxx is intended for
pneumatic operation with liquid lubrication
with Desgranges et Huot 5200 series or Wika
model CPB6000-PX pressures balances.
MNR 530-PCxxx is intended for
hydraulic operation with Desgranges et Huot
5300 series or Wika MODEL CPB6000-HL /
CPB6000-HX pressure balances.
The piston cylinder systems for pneumatic operation with liquid lubrication have a groove set into the inner bore to
which liquid is supplied through two radial holes.
