RAF-P 83 
Pressure Rating PN-10
Nominal Diameter 1.5" - 5"
The RAF-P 83 pressure sustaining valve is a line pressure hydraulically actuated, 3-W plastic pilot. The 83 maintains a minimum upstream pressure, as set on the 3-W plastic pilot, regardless of flow changes.
The RAF-P 83 will fully open should upstream pressure exceed 3-W pilot set pressure. 
The 3-W plastic pilot configuration together with Raphael's patented diaphragm enables smootha and precise upstream pressure control.
Typical Applications
Use RAF-P 83:
* to maintain a constant upstream pressure and to avoid an undesirable high pressure
* is best for agricultural and water supply
