AVG Cold Water Expansion Valve ECV 15mm Green 850KPA related-hills-apollo-exceed-tank-solar-hot-water-sensor-controller and replacing them at theExpansion Control Valve The Expansion Control Valve (ECV) is designed to relieve the increase in pressure caused by the water expansion during the normal heating cycle. It is recommended that an ECV be fitted to the cold water supply line. This will relieve cold water, not hot water, during the heating cycle saving energy and increasing the life of the Pressure Temperature Relief valve (PTR). Some local governments make it mandatory to install an ECV
