To remove the instrument,close the block valve first, and openthe bleed valve to relieve pressureupstream of the block valve.For calibration, by connecting acalibration gauge to the bleed port,able to check the calibration of theinstrument without removing it fromthe installation.3-valveVBR56-3V & VBD56-3V seriesFor measuring flow or level usinga differential pressure transmitter.In operation, both block valves areopen while the equalizer valve isclosed to read a differential pressureto the pressure gauge or transmitter.To zero the instrument, close theblock valve first then open theequalizer valve and zero adjust theinstrument.To remove the instrument, closeblock valves first, then unscrew thebleeding plug to relieve pressurebetween the manifold andinstrument.5-valveVBR56-5V & VBD56-5V seriesFor measuring flow or level using a differentialpressure transmitter or gauge with bleeding,calibration and test functions.In operation, both block valves areopen while the equalizer and bleedvalves are closed to read adifferential pressure to the pressuregauge or transmitter. To zero theinstrument, close block valves andbleed valve, and open the equalizervalve and zero adjust the instrument.For calibration, connect the bleedport to a pressure gauge to checkthe calibration of the instrument.Packing adjustment : Extreme or rapid temperature cycle may require packing adjustment to maintain a leak-free system.Tightening the Locknut on the bonnet is for the packing adjustment.D-Pro V46 series Gauge Root ValvesD-Pro Gauge Root Valves offer a safe way of positioning gauges and installing pressure switches.DesignThis valve is designed to ASME B16.34 Class 2500S316 construction with the minimum schedule 160 pipe wall on valve inletV46GRL Series : Extended body allowing 4.0" of pipe insulationFeatures1/2" and 3/4" male to 1/2" female end connections1/2" female gauge ports standardNon-rotating stem tip designSour gas option to NACE MR0175 latest version3
