The Australian Standard for safety shower and eyewash equipment requires water to be at tepid (15.6 – 37.8degC). Direct sunlight and high ambient temperatures can heat shower and eyewash feed lines above compliant temperatures.
When the water temperature reaches 38degC the valve is fully open and will automatically close once the water temperature reduces to 32degC. This narrow temperature band minimises water loss and ensure the temperature of the flushing fluid is safe and effective.
The H-AHATSP scald protection valve is designed to bleed overheated water out of the system and ensure safe and compliant water temperatures for all safety shower and eyewash users. This precision thermal relief valve is made from a 316 stainless steel body and solid brass ram to ensure suitability in almost all environments.
The scald protection valve has a unique plug and seat design to ensure the most reliable tight shut-off. The valve itself is unaffected by higher pressures or ambient temperatures.
