The high-pressure sample flow control valve in the VREL series comes with a patented design, being an adjustable sample pressure reducer suitable for pressures above 500psig or 35barg. In addition, the tapered rod assembly is precisely machined, moving inside precision holes with the barrel of the VREL. The pressure drop made available by the manufacturer is a function of the length of the rods, inserted into the barrel.
In terms of the features, the adjustable rod-in-tube type design allows for variable pressure drop and flow control, while the item allows precise flow control and pressure control without valve erosion or fluid dissociation. Note that all wetted parts are fabricated from high quality 316 stainless steel, being rated to 5,000psig at temperatures up to 149 degrees Celsius.
