H-AHATSP Scald Protection Valve
H-AHATSP scald protection valves protect against scalding caused by solar radiation or overheating of water in the supply pipe. When installed with safety showers/eye washes the valve will be heated just the same as the piping system. The valve will open to establish flow until the over-temperature water is eliminated and will then modulate closed. The scald protection valve has a unique plug and seat design to ensure the most reliable tight shut-off.
The scald protection valve continually senses water temperature, automatically opens when the water reaches 35°c and bleeds overheated water from safety shower and eyewash supply lines.
