Can the setting pressure of the boiler safety valve be set lower than that specified in the blueprint?
Thread Content
There is a steam boiler in the project with a rated steam generation pressure of 1.6 MPa; the actual steam generation pressure required is only 1.3 MPa. The safety valve specified on the boiler’s drawings has a setting pressure of 1.68 MPa. Can I adjust the setting pressure of the safety valve to 1.35 MPa based on the actual conditions?
Personally, I think it’s fine as long as you’re not worried about the safety valve activating frequently.
This sealing pressure cannot be achieved, and the valve is prone to leakage
If you truly can’t achieve it, that’s fine; adjust it according to the pot’s specifications.
