High pressure control valve
149 °C, 345 bar Sentry Equipment

VREL® - High Pressure Sample Flow Control Valve
Variable Pressure Reducing Element
Model VREL® - Patented Design
The VREL® is an adjustable sample pressure reducer for sample pressures above 500 psig (35 barg). A precisely machined tapered rod assembly moves inside precision holes within the barrel of the VREL®. Pressure drop is a function of the length of the rods inserted into the barrel.

* Adjustable rod-in-tube type design allows for variable pressure drop and flow control
* The VREL® allows precise control of flow and pressure without valve erosion or fluid dissociation
* All wetted parts are fabricated from 316 Stainless Steel
* Rated to 5000 psig at 300ºF (345 barg at 149ºC)
* The VREL® is cleanable in place, "in situ", by retracting the rods without disconnecting or isolating the sample line
