The IC/SP Scald Protection Valve is designed to automatically drain excessively hot water from safety showers and face or eyewash water lines, protecting the operator of the safety fixture from hot water scalding and severe burns. Operation IC/SP scald protection valves are installed within the heated system and are purely water temperature sensing. The IC/SP scald protection valve will initiate flow when the thermostatic actuator senses water temperature above the valve’s set-point (typically 98°F [36.7°C]) and will remain open as long as the discharge water temperature is within 10˚F of the open set-point (typically above 95°F [35°C]). The thermal actuator is always wetted, making this valve preferable for heat traced lines where scald protection flow is not required unless heat tracing fails. Typical Applications A safety hazard for plant personnel can occur when utilizing safety showers, facewash, or eyewash stations if overheating of the pipes caused by solar radiation or steam/electric tracing results in extremely high temperatures at the point of use. For this reason, a scald protection valve should be implemented to protect facility personnel from excessively hot temperatures being released from the fixture and causing severe damage to the skin. The IC/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 IC/SP will be heated just as the pipe system. The valve will open to establish flow until the over-temperature water is eliminated and it will then modulate closed.
