Description

The RAF 8R pressure sustaining control valve maintains a minimum upstream pressure, as set on the 3-W pressure sustaining plastic pilot, regardless of flow changes. The RAF 8R will fully open should upstream pressure exceed 3-W pilot set pressure. The 3-W pilot configuration together with Raphael’s patented diaphragm enables smooth and precise upstream pressure control.
