What it is
The Worcester Bosch 8716122007 is a SIT gas valve supplied as a spare for the manufacturer's Greenstar combi and system boiler ranges. It controls the flow of gas to the burner, opening and closing on demand from the appliance control board and modulating the rate to match the heating or hot water load. The valve sits on the gas train between the isolation cock and the burner assembly.
Signs this part needs replacing
- The boiler fails to light or locks out during the ignition sequence
- No gas pressure reaches the burner when there is a call for heat
- The flame drops out shortly after ignition
- Repeated lockouts with fault codes relating to flame detection or gas supply
- The valve body sticks, leaks or fails to modulate smoothly

- Confirm the part number on the valve currently fitted, as earlier numbers 8-718-651-802-0 and 87186518020 may be present.
- Check whether a gasket or seal kit is needed for the gas train joint.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
