How do I calculate Cylinder Speed (Double-Acting)?

To calculate Cylinder Speed (Double-Acting): Enter Valve flow, Valve opening, Cylinder bore and other values. Click Calculate. INDUGRID computes the result instantly using the formula: v [m/s] = Q_eff [nl/min] / (A [dm²] × 60 × 10). No registration required.

What units does the Cylinder Speed (Double-Acting) calculator use?

The Cylinder Speed (Double-Acting) calculator uses the following units: nl/min, %, mm. SI units are used by default.

💡Manufacturers limit cylinder speeds to 0.1–1.5 m/s. Higher speeds cause excessive end-of-stroke impact and seal wear. Actual speed is always lower than calculated due to hose resistance and fitting losses.

v [m/s] = Q_eff [nl/min] / (A [dm²] × 60 × 10)

Input

Valve flow iNominal valve flow in normal-litres per minute at 6 bar. Typical values: M5=190, G1/8=750, G1/4=1600, G3/8=2000, G1/2=3700 nl/min.

nl/min

Valve opening iPercentage opening of the valve (throttle valve setting). 100% = fully open. Proportional valves: typically 60–80% in practice.

Cylinder bore iInternal bore diameter of the cylinder. Standard ISO sizes: 12, 16, 20, 25, 32, 40, 50, 63, 80, 100, 125, 160, 200, 250 mm.

Stroke length iUseful stroke length of the cylinder in millimetres. Used to calculate fill time.
