The RAF 33P electric valve is a Normally Open (N.O) line pressure hydraulically actuated. The RAF 33 (N.O) valve opens when 3-W electric solenoid valve is de-energized. The RAF 33P (N.O) valve shuts off when 3-W electric plastic 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.
