Pressure Rating PN-16
Nominal Diameter 1" - 14"
The RAF/RAF-P 31 electric is a Normally Closed (N.C.) line pressure hydraulically actuated valve.
The RAF/RAF-P 33 electric is a Normally Open (N.O.) line pressure hydraulically actuated valve.The 3-Way electric solenoid valve changes positions:
The 31 (N.C.) opens when 3-W solenoid valve is energized.
The 31 (N.O.) shuts off when 3-W solenoid valve is de-energized.
The 33 (N.O.) opens when 3-W solenoid valve is de-energized.
The 33 (N.C.) shuts off when 3-W solenoid valve is energized.
The 3-Way electric solenoid valve configuration together with Raphael's patented diaphragm enables smooth opening and surge free shut-off.
* for water suuply systems with medium pressure rating
* for remote operation of hydraulic valve by an electric command
* for irrigation water distribution and field control
