Pressure Rating PN-16
Nominal Diameter 1" - 14
The RAF/RAF-P 70 flow rate control valve is a line pressure hydraulically actuated, 2-W pilot.
Normally, the valve is partly open to allow a constant flow rate. The head loss across the orifice is proportional to the flow rate.
The RAF/RAF-P 70 maintains a constant preset flow rate, as set on the 2-W flow rate pilot, regardless of pressure changes.
The 2-way pilot configuration together with Raphael's patented diaphragm enables smooth and precise pressure control.
Use RAF/RAF-P 70:
* for water supply systems with medium pressure rating
* to eliminate excessive pumping or to limit the water demand
* for irrigation water distribution and field control
