Heatrae Sadia 95605846 3.5 Bar Pressure Reducing Valve | Genuine Heatrae Spare

Heatrae Sadia 95605846 Pressure Reducing Valve

The Heatrae Sadia 95605846 3.5 Bar Pressure Reducing Valve is a genuine replacement inlet-pressure control component listed for selected Tribune and Tribune Premier unvented cylinders.

The valve regulates the incoming cold-water supply to approximately 3.5 bar, helping maintain the controlled inlet pressure required by the cylinder and its safety components. Replacing a worn or faulty pressure-reducing valve can help restore stable water pressure and correct operation of the inlet control arrangement.

Manufactured to the original equipment specification, part number 95605846 should be matched against the existing component and appliance documentation before purchase.

What Does a Pressure Reducing Valve Do?

A pressure-reducing valve (PRV) controls the pressure of the incoming cold water supply before it enters the appliance.

In many areas of the UK, mains water pressure can fluctuate or exceed the level recommended for hot water systems. By reducing the incoming pressure to a controlled 3.5 bar, the valve helps maintain stable operating conditions and protects downstream components.

A faulty pressure-reducing valve can contribute to issues such as:

• Excessive system pressure
• Water discharge from relief valves
• Poor pressure regulation
• Increased wear on internal components
• Inconsistent appliance performance

Replacing a worn or defective PRV helps restore the correct operating conditions.

Compatible Models

The genuine Heatrae Sadia 95605846 3.5 bar pressure reducing valve is listed for the following cylinder ranges:

• Tribune
• Tribune Premier

Always confirm the part number shown on the existing component or check the appliance spare-parts documentation before ordering.

Important: Baxi lists part number S6221 as the pressure reducing valve used across Tribune, Tribune Premier, Santon Premier and Santon Tribune Premier models. Do not assume that 95605846 and S6221 are interchangeable without verifying the required replacement part.

Technical Specification

Signs a Pressure-Reducing Valve May Need Replacing

Over time, pressure-reducing valves can become affected by wear, debris or limescale.

Common symptoms include:

• Water pressure higher than expected
• Relief valve discharge
• Fluctuating system pressure
• Poor appliance performance
• Visible leaks from the valve body

If these symptoms occur, the valve should be inspected and, where necessary, replaced with the correct genuine replacement part.
