RAF 83B pressure sustaining valve is line pressure hydraulically actuated, 3-W pilot.
The RAF 83B maintains a minimum upstream pressure, as set on the 3-W pilot, regardless of flow changes.
The RAF 83B pressure sustaining valve will fully open should upstream pressure exceed 3-W pilot set pressure.
The 3-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
