How can you tell if your using the right pressure relief valve on a boiler?

I have a Weil Mclain CGT boiler. Here is a picture of the side plate. https://imgur.com/a/9BEeHxx The max pressure is 30 psi and the input btu/hr is 133,000 for the boiler. I bought a Zurn pressure release valve P1000AXL-30C. The tag on the relief valve says 30 psi and 510,000 btu/hr. I'm assuming that this pressure relief valve won't have any issues working with my boiler. Let me know if you see any issues. Thanks!
