General information
The temperature and pressure relief valves (TP) 309 series are made
by Caleffi S.p.A in compliance with the essential safety requirements
laid down by Directive 97/23/EC of the European Parliament and the
Council of the European Union for harmonisation of Member States
with regard to pressurised equipment.
Function
The TP relief valve controls and limits the temperature and pressure
of the hot water contained in a domestic storage heater and prevents
it from being able to reach temperatures of over 100°C, with the
formation of steam.
On reaching the settings, the valve discharges a sufficient amount
of water into the atmosphere so that the temperature and pressure
return within the system's operating limits.
This particular series of valves is certified as conforming to the
performance requirements of the European standard EN 1490
(for settings of 4 - 7 - 10 bar).
