Altecnic Ecopas 1 1/4 Bypass Valve 519700

The Altecnic Ecopas 1 1/4 Bypass Valve is a bypass valve manufactured by Altecnic for heating systems. It forms part of the Ecopas range and is intended for use with Altecnic radiator valves, where it provides a controlled bypass path in the system. Its function is to maintain circulation through the boiler circuit when the demand from the radiator valves falls away.

• The bypass valve no longer holds a consistent setting, so system differential pressure drifts.
• Radiators heat unevenly or the boiler cycles short because the bypass path is not regulating flow correctly.
• The valve body or connections show signs of weeping or leakage.
• The adjustment mechanism has seized or become difficult to set.
• Increased circulation noise from the pump or pipework where the bypass is not relieving flow.

• Confirm the connection size is 1 1/4 and matches the pipework or valve it is being fitted to.
• Check that the installation is an Altecnic radiator valve arrangement, as listed in the fitment data.
• Verify the existing bypass valve's setting and orientation before removal so the new unit can be set to match the system requirements.
• Confirm whether the system is sealed or open vented, and that the valve is suitable for the installation.
