Pratt Anti Freeze Valve Only 1.7°C Rated Temperature

Anti-Freeze Valve for Safety Showers and Eyewash Stations

Designed to safeguard emergency equipment in cold conditions, this Anti-Freeze Valve automatically releases water when temperatures approach freezing—helping to prevent blocked flow and equipment failure. It activates at -1.7°C and closes once temperatures reach -4.4°C, reacting to water temperature alone (not pressure).

Constructed entirely from stainless steel—including the body, plug, spring, and fittings—this robust valve ensures long-lasting performance in harsh environments.

Temperature-sensitive, not pressure-dependent

Stainless steel construction for durability

Compliant with AS4775 standards
