Expansion vessel connection sets

 
 Expansion vessel connections sets and kap valves enable the standard-compliant connection and maintenance of diaphragm expansion vessels in closed heating systems in accordance with DIN EN 12828 without having to drain the system. The pre-assembled connection groups integrate a safety valve, pressure gauge, automatic quick air vent and a shut-off device (cap valve or quick coupling) secured against unintentional closing. Suitable for expansion vessels up to 24 litres.
