TRAC STYLE ‘J’ COMBINATION PRESSURE & TEMPERATURE REGULATOR

The TRAC Style ‘J’ combination pressure and temperature regulator is basically an internal pilot operated steam pressure reducing valve with the addition of a provision which automatically modifies the reduced pressure setting as a function of the process temperature by means of a temperature signal feedback circuit into the pilot section. The regulator will automatically control steam flow through the valve in response to changes in the temperature of the controlling medium and/or changes in outlet pressure. The regulating valve requires no external source of power to operate the valve or to detect changes in the temperature of the controlling medium. The valve can be set to control at any temperature within the limits of the temperature range stamped on the nameplate. The standard ranges for Style ‘J’ valves are provided with a 100 deg.F adjustable temperature span.

The TRAC Style ‘J’ combination pressure and temperature regulator should be specified when close temperature control in required. Applications are normally limited to heating situations where the heating medium will be steam, and the steam supply available is at a higher pressure than needed for heating.

Any water heater, fuel oil heater, or lube oil heater operated off of a high-pressure steam source can use a Style ‘J’ Combination Pressure and Temperature Regulator advantageously. Process systems of all kinds- dryers, charge heaters, reactors, heat exchangers, cookers, coaters, evaporators, curing ovens, and kilns are potential Style ‘J’ applications.

Should the thermostatic element fail in operation, the temperature signal feedback circuit into the pilot section would no longer modify the reduced pressure setting as a function of the process temperature. Although process temperature control would be lost, the Style ‘J’ valve would continue to regulate outlet pressure and prevent any catastrophic over pressure condition within the system.

The Style ‘J’ regulator is manufactured in accordance with the following military specifications:
MIL-V-19772A and MIL-DTL-19772B TYPE IV  SERIES 100 (BRONZE) and 150 (STEEL)
