What it is

The Gledhill SG021 is a combination valve for unvented hot water cylinders, supplied under the Advanced Water brand. It groups the pressure reducing, expansion relief and check valve functions into a single 22mm assembly. Its 3/4.5 bar rating sets the operating pressure reduction and relief thresholds for the cylinder it serves.

Before you order

  • Confirm the valve rating matches the cylinder installation requirements before fitting.
  • Check the pipework connection size on the existing installation is 22mm.
  • Confirm the cylinder make and model to ensure the correct valve assembly is specified.
  • Have the cylinder manufacturer's installation instructions to hand for commissioning and pressure settings.
