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.

Description

Siemens AGA22 is a yellow spare spring for actuators and control mechanisms. It is designed for use in Siemens equipment for gas burners and heating systems. In a gas valve, it helps set the opening pressure or closing force; in a pressure regulator, it sets the downstream pressure.

Further details

Durability	high resistance to wear and loads
Function	Determining the opening pressure or closing force of the valve disc
Installation notes	Internal part of a sealed or semi-sealed assembly
Material quality	High-quality materials resistant to mechanical loads and long-term operation

Choosing and fitting

Springs of this type are selected by free length, wire diameter, coil count, and spring rate. A replacement must match the original part's dimensions and rate exactly to restore the designed force and travel. Before ordering, measure the old spring or verify the manufacturer's part number. The surrounding assembly may require disassembly and re-calibration after installation.

Signs of failure

When a spring of this type weakens or breaks, actuators or valves may fail to open, close, or maintain the correct set point. This can lead to unstable combustion or a safety lockout. A spring that is too stiff can cause the valve to open late or not at all; a spring that is too soft may allow premature opening or loss of regulation.
