Pressure Rating PN-10
Nominal Diameter 1" - 6D"
The RAF/RAF-P 63-31 is a Normally Closed (N.C.) pressure reducing valve.
The 63-31 is an electric on/off valve, controlled by a 3-W plastic solenoid valve. When the solenoid is energized the valve opens and performs as a pressure reducing valve, maintaining the preset pressure constant regardless of flow-rate or upstream pressure fluctuations.
The 3-W plastic pilot has a spring loaded membrane, a downstream sensitive and can be preset to a desirable downstream pressure.
The 3-W plastic pilot configuration together with Raphael's patented diaphragm enables smootha dn precise downstream pressure control.
* for irrigation, water distribution and flow control
When downstream pressure should be reduced, the valve is commanded to open
