VVR sizing

The calculator below will help to determine the required volume and VVR size.

The VVR can:

Please note that motors, double rod cylinders and rotary actuators have no differential volume.

Which VVR do you need?

Differential volume - Cylinder type 1

Differential volume - Cylinder type 2

Differential volume - Cylinder type 3

Differential volume - Cylinder type 4

Thermal expansion

%

Note 1: Initial volume = Network volume + pump & motor housing volume + cylinder tube volume

Note 2: The constant 10% covers for; -30°C to + 125°C (-22°F to +257°F) temperature range, which is very conservative.
