The RAF 33 electric valve is a Normally Open (N.O) line pressure hydraulically actuated.
The 3-W electric solenoid valve changes positions: The RAF 33 (N.O) opens when the 3-W solenoid valve is de-energized.
The RAF 33 (N.O) shuts-off when 3-W solenoid valve is energized.
The 3-W electric solenoid valve configuration together with Raphael’s patented diaphragm enables smooth opening and surge free shut-off.
Maximal Nominal Pressure: 16 bar
