Pressure Rating PN-16
Nominal Diameter 1" - 6D"
The RAF/RAF-P 682 pressure reducing & sustaining valve is a line pressure hydraulically actuated, 2-W pilot.
The RAF/RAF-P 682 maintains a minimum upstream pressure, as set on the 2-W pressure sustaining pilot and a maximum downstream as set on the 2-W pressure reducing pilot, regardless of flow changes.
The 2-way pilot configuration together with Raphael's patented diaphragm enables smooth and precise pressure control.
Use RAF/RAF-P 682:
* for water supply systems with medium pressure rating
* to define two pressure zones along a supply line
* for irrigation water distribution and field control
