AVG Expansion Control Valve 20mm - 550kPa, Lead Free, DR Brass, WaterMark AS1357.1 | ECV20-550-LF wall hung basin It reduces and stabilises incomingThe AVG ECV20 550 LF is a 20mm (3 4") lead free expansion control valve set to 550kPa, designed to absorb the pressure increase caused by thermal expansion in a hot water storage system. Fitting an ECV to the cold water inlet prevents hot water discharging from the pressure temperature relief (PTR) valve on every heating cycle protecting the PTR valve, saving energy, and extending the life of the whole system. Both PTR and ECV valves are safety
