The RAF 82 pressure sustaining/relief valve is line pressure hydraulically actuated, 2-W pilot. The RAF 82 maintains a minimum upstream pressure, as set on the 2-W pressure sustaining pilot, regardless of flow changes.
The RAF 82 pressure sustaining/relief valve will fully open should upstream pressure exceed 2-W pilot set pressure.
The 2-W pilot configuration together with Raphael’s patented diaphragm enable smooth and precise upstream pressure control.
Maximal Nominal Pressure: 16 bar
Setting Range: 0.6 to 6 bar
