As a genuine Glow‑Worm spare part, the 20061610 safety valve is manufactured to strict original equipment specifications for calibration accuracy, reliability, and durability. A correctly functioning safety valve is a critical protective element in any pressurised heating system: it acts as a fail‑safe when routine pressure control (such as via the expansion vessel and filling loop) is insufficient or when there are sudden pressure spikes caused by thermal expansion. By ensuring that pressure is limited to a safe threshold in this case 3.5 bar the valve helps safeguard the boiler’s integrity and prevents events such as heat exchanger rupture, pipe joint failure, or seal degradation that could lead to leaks, system shutdowns, or costly repairs.
Over time, safety valves can become stiff, corroded, or blocked by limescale and debris carried in the water system, which may compromise their ability to open at the correct pressure. A sticking or faulty valve might not relieve excess pressure promptly, risking internal component stress, or it might leak prematurely, causing pressure loss and frequent need for repressurisation. Replacing a worn or unreliable valve with this OEM component restores proper overpressure protection, enhances system safety, and provides peace of mind that the boiler is protected against abnormal pressure conditions. Because this part directly affects system safety, installation should always be carried out by a qualified heating engineer, ensuring correct mounting, secure connections, and compliance with safety and performance standards.
