What it is

This is a Donkin non-return valve (N.R. valve) with a 3in flanged connection, carrying the part reference 590--G-G--D---. It is listed under the Oil Spares brand within the Nu-Way model range and is catalogued for boiler applications. The valve allows flow in one direction only and closes against reverse flow in the line it is fitted to.

Before you order

  • Confirm the 3in flanged connection matches the pipework and mating flange at the intended installation point.
  • Check the flow direction marked on the valve body against the direction of flow in the line before fitting.
  • Verify that the part reference 590--G-G--D--- matches the reference on the existing valve or the specification for the job.
  • Confirm that the valve's stated pressure and temperature ratings suit the system it is being fitted to.
