RAF-P 683

RAF-P 683 
Pressure Rating PN-10
Nominal Diameter 1.5" - 5"
The RAF-P 683 pressure and sustaining valve is a line pressure hydraulicaaly actuated, 3-W plastic pilot.
The RAF-P 683 maintains a minimum upstream pressure, as set on the 3-W pressure sustaining plastic pilot and a maxiumum 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 plastic pilot configuration together with Raphael's patented diaphragm enables smootha dn precise downstream pressure control.
Typical Applications
Use RAF-P 683:
* to define two pressure zones along a supply lines
* for irrigation water network
