Air supply piping 10 mm or 3/8" for all actuators.
Pipe sizes are nominal, i.e. approximately outer diameter. Inner diameter is typically 2 mm smaller.
x = Standard pipe size used in Neles control valves.
(x) = Minimum pipe size (if smaller than standard).
*) Spool size 2 is preferred for accurate control and standard for Neles control valves.
Spool size 3 can be used if fast full stroke times are required.
Stroking times have been measured without valve.
Tests have been done with supply pressure of 5 bar.
