What it is
The Worcester Bosch isolating valve (CH) is a service valve used within the appliance to shut off water or gas flow when the boiler is being worked on or drained down. It is supplied by Worcester Bosch under part number 87161082560 and is listed against the Greenstar Heatslave range of oil-fired boilers. Its job is to isolate the relevant circuit cleanly so that maintenance, component replacement or pressure work can be carried out without draining or disturbing the rest of the system.
Signs this part needs replacing
- The valve will not shut off fully, so flow continues when the appliance is isolated.
- Water weeps from the spindle or around the body of the valve.
- The handle is stiff, seized or turns without operating the valve.
- A drip appears at the valve when the boiler is drained or refilled.
- Isolation for routine servicing becomes difficult because the valve no longer holds.
Before you order
- Confirm the appliance model and serial number against the compatibility list before ordering.
- Check the existing valve and any associated seals or washers, as a seal kit may be needed to complete the repair.
- Note the alternative part number 1015403 when cross-referencing older documentation.
