Ok, I'll ask the EPC why this wasn't done. Wish we could fire them, the owner of the EPC is a significant shareholder in our company!
Pump pressure at zero discharge is 215psi. If I assume 50% overpressure (to be conservative), that's 322psi, which is above the rated 276psi. Wouldn't the PRV...
Appreciate the comments guys. Thanks.
Our consultant is also claiming he won't guarantee the system if the EPC doesn't upgrade to class 300.
Rmw-I remembered when sizing motors for pumps, you normally move 1 step higher. So for valves, 1 pressure class higher. But I like the reasoning for...

We will be using seawater for our fire protection. Valves will be nickel aluminum bronze.
I believe class 150 NAB valves are rated at 19bar/276psi which is still higher than 245. Pump pressure at zero discharge is 215psi.
The water is...
