Sentry VREL®

The Variable Pressure Reducing Element (VREL®) effectively reduces pressure, helps to adjust sample flow and protects online instruments. VREL® is used for samples with pressures above 500 psig (34 bar).  The VREL® reduces pressure over a large surface area, has a wide adjustment range (56 turns from full open to closed) and is easily cleanable in place.  These features offer better sample flow control, ease of maintenance, and a longer service life than other pressure reducing devices.
