Description
The Caleffi temperature - pressure relief valves are used to control
and limit the temperature and pressure of hot water contained in a
domestic storage cylinder, preventing the water from reaching 100°C. When the set conditions are reached, the valve discharges a sufficient amount of water to allow the temperature or pressure to return within the system’s operating limits.
The valves have been designed for use on unvented hot water systems.Tech Spec
