The calculator below will help to determine the required volume and VVR size.
The VVR can:
- either be installed on OEM equipment or retrofitted onto existing machines;
- be installed in series or parallel, for larger volume requirements;
- operate in a temperature range of -20°C to +107°C (-4°F to +225°F). With the reduced volume, in cold start situations the warm up time will be much quicker. A heater pad can be installed for operating temperatures bellow -20⁰C (-4⁰F). See VVR options.
Please note that motors, double rod cylinders and rotary actuators have no differential volume.
