RAF 683B
The RAF 683B pressure reducing & sustaining valve is a line pressure hydraulically actuated.
The RAF 683B maintains a minimum upstream pressure, as set on the 3-W pressure sustaining pilot and a maximum downstream as set on the 3-W pressure reducing pilot, regardless of flow changes.
The 3-way pilot configuration together with Raphael's patented diaphragm enables smooth and precise pressure control.
Typical Applications:
Use RAF 683B:
* for water supply systems with medium pressure rating
* to define two pressure zones along a supply line
* for irrigation water distribution and field control
