Pressure Rating PN-10
Nominal Diameter 1.5" - 5"
The RAF-P 83-31 is a Normally Closed (N.C.) pressure sustaining valve.
The RAF-P 83-31 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 sustaining valve, maintaining the preset pressure constant regardless of flow-rate or pressure fluctuations.
The 3-W plastic pilot can be preset to a desirable minimum upstream pressure.
The 3-W plastic pilot configuration together with Raphael's patented diaphragm enables smootha dn precise downstream pressure control.
Use RAF-P 83-31:
* for irrigation, water distribution and flow control
When downstream pressure should be reduced, the valve is commanded to open
