Abstract: New developments during 1973 that will be utilized heavily in the natural gas industry include a high pressure pilot operated gas regulator and a new approach to noise abatement trim in control valves and regulators. These products have recently been offered for sale and a discussion of each follow. The 298H is a pilot operated gas regulator that was designed for operating pressures of up to 1440 psig inlets and 300 psig outlets. It is a new high pressure addition to the existing 298 series of devices. The 298H is a true two-path pilot operated gas regulator. This allows it to be spring closed, sensitive to any load change and very fast in responding to these load changes. In addition, in-line maintenance is very easily accomplished with this device, As with any new design many features are incorporated into it. The list of features for the 298H are lengthy and therefore only the more important ones will be listed here.
