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.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.

Description

This bypass oil valve is installed in the oil circuit between the pump and nozzle assembly, diverting excess fuel back to the tank or pump inlet to stabilize pressure. It handles flows from 300 to 6000 l/h, pressures up to 9 bar, temperatures up to 150 °C, viscosity up to 450 mm2/sec. Ambient range is -10 to +90 °C, storage -10 to +60 °C. It is suitable for single-pipe systems requiring recirculation.

Further details

Adjustment mechanism	screw and one of five springs
Adjustment method	Screw and one of five springs
Application	Single-pipe and two-pipe oil heating systems
Construction type	compact solution for variable flow systems
Design features	pressure relief and flow regulator; relieves excess pressure from line P to return line T; pressure adjusted via screw and one of five springs
Temperature	max. 150 °C

Choosing and fitting

For this type of valve, verify the hydraulic configuration (single-pipe or two-pipe), required capacity and pressure range. The connection threads and shaft orientation must match the mounting pattern on the pump body. Before ordering, compare opening pressure and flow characteristics with pump output and nozzle rating. Also check that the valve's pressure adjustment range (via screw and spring selection) suits the system.

Signs of failure

Common failure modes include leaking seals, blocked bypass ports, or a stuck regulating piston. This causes unstable firing rates, poor cut-off, or pump cavitation. Check seals and ports for blockage and ensure the piston moves freely.
