Pressure Rating PN-16
Nominal Diameter 1" - 14
The RAF/RAF-P 83B pressure sustaining valve is a line pressure hydraulically actuated, 3-W pilot.
The RAF/RAF-P 83B maintains a minimum upstream pressure, as set on the 3-W pilot, regardless of flow changes.
The RAF/RAF-P 83B pressure sustaining valve will fully open should upstream pressure exceed 2-W pilot set pressure.
The 3-way pilot configuration together with Raphael's patented diaphragm enables smooth and precise pressure control.Typical Applications:
Use RAF/RAF-P 83B:
* for water supply systems with medium pressure rating
* to maintain a constant upstream pressure and to avoid an undesirable high pressure
* for irrigation water distribution and field control
