The RAF 68R maintains a minimum upstream pressure, as set on the 3-W pressure sustaining plastic pilot and a maximum downstream as set on the 3-W pressure reducing plastic pilot.
The minimum upstream and the maximum downstream pressure are maintained regardless of flow changes.
The 3-W pilot configuration together with
Raphael’s patented diaphragm enables smooth
and precise pressure control.
Maximal Nominal Pressure: 10 bar
