As a genuine Glow‑Worm part, the 800442 gas section is built to original equipment specifications, ensuring that its mechanical operation, pressure regulation and electrical interfacing match the factory design for the boilers it is intended to fit. This precision is essential because the gas valve directly affects combustion safety and efficiency — if gas delivery is too low, the boiler may fail to maintain a stable flame; if too high, combustion can be unsafe or inefficient, potentially leading to increased emissions, higher fuel use, or fault codes. A quality OEM valve also ensures that the control board’s signals are translated into smooth, repeatable responses at the burner, helping the boiler modulate effectively under different loads.
Gas valves like the 800442 unit work under continuous thermal and mechanical stress and over time can wear due to repeated cycling, build‑up of combustion by‑products, or contamination. Symptoms of a failing gas section can include delayed ignition, flame instability, persistent lockouts, or unusual noise during firing. Replacing a worn or defective valve with this factory‑approved part restores accurate gas metering and improves combustion performance, which in turn helps reduce nuisance faults and extend the life of related components like the ignition system and flame detector. Because this component is directly tied to safe gas control, installation must be carried out by a qualified Gas Safe engineer, ensuring correct connection, calibration, and compliance with gas safety regulations.
Glow-Worm provide a 1 year warranty on all spare parts. Electrical Deals Direct now sells a wide range of spare parts. If you cannot see the item you require on our website, please call 01934 253600 or email [email protected] for more information.

Standard delivery for all orders over £150 ex-VAT are free of charge.
If we can speed this up, we will, but you can also select Express Delivery when you check out and get your purchase more quickly (usually the next working day, subject to a 1pm cut-off): there is an extra charge for this ranging from £5 to £29.99 depending on the products you are buying.
We partner with several of the best UK carriers (such as TNT, Royal Mail, DPD etc) depending on the type of product and the warehouse it is coming from, and also with some pallet companies for larger items. All of these operate during normal Monday – Friday working hours, and we expect all deliveries to arrive in 5 days. For more details checkout this page.
For all Gledhill Cylinders, a flat delivery charge of £27.50 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
