What it is
The Jeavons J78RS is a 0.5 in gas pressure regulator supplied complete with a 10-23MB spring. It regulates downstream pressure at the burner on boiler plant, with the spring setting determining the pressure the regulator holds. The part is listed under the OIL SPARES brand.
Before you order
- Confirm the existing regulator is a J78RS and that the pipework connection is 0.5 in.
- Check that the 10-23MB spring supplied matches the pressure range required for the burner setting.
- Verify the regulator body and spring are serviceable as a pair before fitting.
