Pressure Rating PN-10
Nominal Diameter 1" - 6D"
The RAF/RAF-P 73 flow rate control valve is a line pressure hydraulically actuated, 3-W plastic pilot. Normally the valve is partly open to allow constant flow rate. The head loss across the orifice is proportional to the flow rate.
The 73 maintains a maximum preset flow rate, as set on the 3-W flow rate pilot, and calibrated orifice regardless of pressure changes. The 3-W pilot configuration together with Raphael's patented diaphragm enables smooth and precise flow rate control.
* for irrigation water distribution and field control
* to eliminate excessive pumping or to limit the water demand
* is a cost effective option for low pressure agricultural supply
