What it is

The Oso 90423 is a sole pressure relief valve with an 8 bar set pressure, manufactured by Oso. It discharges water when system pressure reaches the valve's rated pressure, protecting the cylinder and associated pipework from over-pressurisation. It falls within the pressure relief and safety valve category.

Before you order

  • Confirm the system or cylinder requires an 8 bar relief valve. Relief valves are selected by set pressure and must match the design pressure of the installation.
  • Check the connection size and thread of the valve being replaced against the Oso 90423 before ordering.
  • Verify the part number 90423 matches the valve currently fitted.
  • Confirm the discharge pipework can take the full flow from the valve, as required for the installation.
