What it is

The Worcester Bosch 87161424170 is an isolation valve with a 22mm x 1-1/2 inch connection, used to control water or gas flow within the appliance. It is a Worcester spare part listed under the Valves General, Assembly category and is built for the Danesmoor oil boiler family and related Worcester models. Fitting an isolation valve allows flow to be shut off locally at the appliance so that servicing or component replacement can be carried out without draining or disturbing the wider system.

Signs this part needs replacing

  • Water weeping from the valve body, spindle or gland
  • The handle turns but flow through the valve does not stop
  • A seized or stiff spindle that will not operate by hand
  • Damp staining or corrosion around the valve connections
  • Difficulty isolating the appliance when carrying out service work

Before you order

  • Check the appliance model and GC number against the compatibility list before ordering.
  • The previous Worcester number for this valve is ZCVLV008.
  • Confirm the connection on the appliance matches the 22mm x 1-1/2 inch size of this valve.
  • Have the appliance serial number to hand when verifying fitment.
