Table a.
Volumes in dm3 for gas valves like Honeywell VE-series (Vp) with pipe length L (including V1 and V2). For combi blocks, like
VQ-
M series and direct linked valves, use the values shown under L=0m.

If L = 0m it means that valves are directly linked without pipe connections. Also applicable
for combi-blocks (VQ-M series).
