The TRAC Style ‘P’ (electrically failsafe) temperature regulator is a pilot-operated valve specifically designed to control steam supply to shipboard instantaneous heater systems. The valve will automatically regulate steam flow to the heater coil in response to changes in hot water temperature at the heater outlet. The standard range for Style ‘P’ valve is 120°-180° F. Other ranges are available and are provided with a 60° F adjustable temperature span.

To prevent overheating upon failure of the thermostatic element, the valve is provided with an electrically operated safety feature. A solenoid valve is incorporated on the inlet side pilot tube line. The solenoid provided is normally closed. In order to operate the temperature regulator, the solenoid valve must be energized. Upon failure of the thermostatic element, loss of electric current to the solenoid, or if any other valve malfunction causes the hot water outlet temperature to overheat, the solenoid valve will close, shutting off inlet pressure to the valve piston, thereby closing the temperature regulating valve.
