What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Further details

Application	Kromschroder gas valves VA 1, VA1/B, VC 1 (size 1)
Kit Contents	Complete set including double-block seal, retaining frame, flange o-rings and other elements
Materials	High-quality elastomers resistant to gas, high temperatures and pressure
Suitable configurations	Double-block valve assemblies and series connections

Choosing and fitting

Seal kits of this type are selected by exact valve series and manufacturer part number. They are not interchangeable between series; the kit must match the valve body, not just the nominal size, because internal seal forms and port arrangements differ. Before ordering, confirm the valve series and model markings on the valve body. Install using the complete kit, as individual gaskets may not have correct material pairing.

Signs of failure

Seals and gaskets deteriorate over time due to thermal cycling and exposure to gas or combustion air. This can lead to gas leaks, compromising burner performance and safety. A leaking valve may show signs of gas smell, pressure drops, or unstable flame. Regular inspection and replacement of all seals are necessary to maintain tightness.
