The HAT/SP, scald protection valve, should be installed at the highest point on an emergency safety station to sense and automatically bleed off the excessively hot water continuously. When installed in the ambient sensing position (standard flow), the actuator will respond to ambient temperature to initiate flow and then respond to water temperature once flow is established; when installed in the fluid sensing position (reverse flow), the actuator will always respond to water temperature.
A safety hazard for plant personnel will occur through solar radiation or overheating caused by steam or electric tracing resulting in extremely high temperatures at the point of use. The HAT/SP valve prevents this safety hazard. When installed in safety showers, eyewash stations, and other locations exposed to the same source of overheating as the system, the HAT/SP will be heated just as the pipe system. The valve will open to establish flow until the overtemperature water is eliminated and it will then modulate closed.
