Adjustable bypass valve for central-heating systems
Published: January 2008
An adjustable bypass valve from Altecnic for central-heating systems prevents the pump working against a closed circuit when all control or thermostatic radiator valves are close. The Eres valve ensure a flow recirculation proportional to the number of valves closed, while limiting the maximum differential pressure generated by the pump. In systems with a traditional boiler, the valve would normally be fitted between the system flow and return ends, allowing the pressure to be controlled and the passage of a minimum flow through the heat generators. In systems with a condensing boiler, it is preferable to fit the valve directly between the upstream and downstream sections of the pump. An Eres valves is adjusted by a calibrated cap.
