Use of pneumatic components

[2010FRC1784]

Hello GDC,

<R72> does not specifically address flow controls, dump valves, manifolds.
Can you please clarify, in the event these components meet the 0.32Cv and 1/8 npt restrictions:

1. are dump valves permitted (aka shuttle valves, non solenoid) similar to Festo 9798

2. are flow controls permitted

3. are manifolds / distributors permitted, similar to Festo 190779

Thank you

[GDC]

1. No.
2. These are considered "connecting fittings" and are covered under Rule <R72-F>.
