What it is

This is a 4 bar safety valve, part number 7612416, manufactured by Potterton Commercial. It is a pressure relief valve fitted to Potterton Commercial boiler plant, opening at its set pressure to discharge water and protect the appliance and system from over-pressure. It is rated at 138 kW.

Signs this part needs replacing

  • Water continually discharging from the valve outlet when the system is below its set pressure
  • System pressure failing to hold, with repeated top-ups required
  • The valve failing to reseat after a pressure release event
  • Scale, corrosion or debris visible at the valve seat or outlet
  • Visible leakage or weeping from the valve body or connections

Before you order

  • Confirm the existing valve is rated at 4 bar before ordering a replacement
  • Check the part number 7612416 against the appliance data plate or existing component
  • Verify the appliance model against the fitment list above, as cascade kit variants differ
  • Confirm the valve connection size and thread on the appliance match the replacement before fitting
