Worcester 15 24 SBi Bosch RX2 RSF 22mm Isolating Service Valve 87161480060

Product Overview

The Worcester Bosch 22mm Isolating Service Valve (Part Number: 87161480060) is a hydraulic isolation component designed for selected Worcester Bosch boiler systems.

The valve forms part of the boiler's heating water connection arrangement, allowing the relevant section of the central heating circuit to be isolated for servicing and maintenance.

The 22mm connection size is associated with the boiler's flow and return isolation arrangement. Correct valve operation and sealing are important for maintaining secure hydraulic connections during normal heating operation.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished valves should be professionally inspected and tested for correct operation and leakage before installation.

Technical Insight & Common Failure Symptoms

The isolating service valve is a mechanical shut-off component used within the boiler's hydraulic connection system.

It allows the relevant water connection to be isolated when servicing or maintenance is required. Unlike an automatic control valve, it is intended for manual isolation rather than regulating heating temperature or system pressure.

Over time, isolating valves may be affected by mechanical wear, corrosion, internal deposits or deterioration of their sealing components.

Possible symptoms that may indicate an isolating valve or associated hydraulic connection problem include:

• Water leakage around the valve body or connections.

• Valve failing to open or close correctly.

• Valve mechanism becoming stiff or difficult to operate.

• Visible corrosion or deterioration.

• Damaged or worn sealing surfaces.

• Heating system pressure loss associated with leakage.

• Valve failing to provide effective isolation when closed.

These symptoms do not necessarily confirm a faulty isolating valve, as similar problems may result from damaged seals, pipework connections or other hydraulic components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 87161480060) is associated with selected Worcester Bosch 15 SBi and 24 SBi boiler systems and other compatible Worcester boiler hydraulic connection arrangements.

Please verify the exact boiler model, GC number, part number, 22mm connection specification and valve configuration against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler isolating valves and associated pressurised hydraulic components should only be inspected, removed or installed by a suitably qualified and competent heating engineer.

Always isolate the appliance and allow the heating system to cool before carrying out any work. The relevant water circuit must be safely isolated and depressurised before removing the valve. Follow the manufacturer's servicing instructions and complete all required pressure, leakage and operational safety checks before returning the boiler to service.
