Heatline Boiler Diverter Valve By Pass Group (D020113004)
The Diverter Valve By-Pass Group Assembly (Part No: D020113004) is a critical structural hydraulic distribution block engineered for the space-saving mechanical plumbing layouts within Heatline combination boilers. This heavy-duty manifold housing acts as the central safety and circulation interface for the appliance's primary water loop, integrating the internal bypass network directly with the main diverter valve track. When system zone valves close or radiator circuits build excessive resistance, this assembly dynamically regulates a calibrated relief pathway, maintaining minimum design flow velocities through the main heat exchanger to protect the boiler from localized thermal shock, overheating, and pressure spikes.
-
Hydraulic Core Stabilization: Maintains safe, balanced water circulation across the primary circuit even under fluctuating system loads or restricted radiator circuits.
-
Premium Structural Compound: Manufactured from high-tensile, heat-stabilized materials designed to resist long-term internal pitting, surface scaling, and micro-leak tracking.
-
Overheating Prevention: Instantly balances transient system pressure spikes and prevents localized boiling or thermal blockages within the combustion chamber during quick mode transitions.
-
Direct Mechanical Alignment: Precision-stamped configuration ensuring drop-in seating against the central heating return lines and the secondary domestic hot water plate heat exchanger.
Compatible Models:
-
Heatline Monza 24C (2011–2012) — 47-157-21
-
