Firebird Pressure Relief Valve (PRV) MKI – 3 Bar – ACCCOMSRV
Essential Safety Component for Firebird Boilers

Product Summary

The Firebird MKI Pressure Relief Valve (PRV) – 3 Bar (ACCCOMSRV) is a vital safety component designed to protect Firebird boilers from excessive pressure build-up. Operating at a factory-set release pressure of 3 bar, this high-quality valve safely discharges water when pressure exceeds safe operating levels—preventing potential damage to the boiler, pipework, or heating system.

This PRV is suitable for early Firebird MKI models and is ideal for both reactive replacement and scheduled maintenance tasks.
