What it is

The RWC ZRC214045 is a pressure relief valve cartridge rated at 4.5 bar, supplied under the Advanced Water brand.

The cartridge opens at its set pressure to discharge excess pressure and protect the cylinder and its components.

Before you order

  • Check the existing valve assembly accepts a cartridge of this format before ordering.
  • Verify the part number ZRC214045 against the cartridge being replaced.
