What it is

The Ravenheat 50001 isolation valve kit complete is a flow and return isolator assembly for Ravenheat CSI 85 series gas boilers. It allows the heating circuit to be isolated at the appliance so the boiler can be drained, serviced or worked on without draining the whole system. The kit is supplied as a complete pack.

Signs this part needs replacing

  • Water weeping or dripping from the valve body or spindle
  • The valve spindle is seized and will not turn
  • The valve passes water when closed, so the appliance cannot be isolated
  • Scale or corrosion visible around the valve connections
  • Damp staining or residue beneath the valve after servicing

Before you order

  • Confirm your boiler model against the fit list above
  • Check the existing valve arrangement on the appliance before ordering
  • Confirm whether the flow, return or both valves require replacement
