Note) ● The cylinder average speed is referential at 72.5psi (0.5MPa) of pressure, 30% of load factor and 1m of tube length.
● The cylinder speed can vary according to the configuration of piping and fittings.
● The data in the above table represents the value when ø8mm Push-In Fitting is used on 4(A) and 2(B) ports of
SVA20S-D24.
