What it is
The Worcester Bosch 87161134080 is a 7 bar temperature and pressure relief valve for Worcester Bosch Greenskies cylinders. It is a safety device that opens and discharges water when the cylinder's internal pressure or temperature rises above its set threshold, protecting the cylinder shell and the components around it from over-pressurisation. The valve is a direct replacement for the unit originally fitted to these cylinders.
Signs this part needs replacing
- Water weeping or running continuously from the valve discharge outlet
- Discharge pipe passing water when the cylinder is cold and at normal working pressure
- The valve failing to reseat and seal after a pressure or temperature event
- Scale, corrosion or debris visible around the valve seat or outlet
- Cylinder pressure or temperature climbing beyond normal limits without the valve discharging
Before you order
- Confirm the part number 87161134080 against the valve currently fitted to the cylinder
- Check the cylinder model and serial plate to confirm Greenskies compatibility
- Cross-reference the alternative number 1021886 against older documentation
- Pressure and temperature relief work on a cylinder should be carried out by a competent engineer
