The bearing pad is a 1/2" elastomeric pad intended to isolate the valve base from the vibrations in the the piping system. I'm not sure what the justification is for the 12 psi. The manufacture's data sheet says that the "lowest" listed pressure capacity is 50 psi.
In this application the engineer of record has specified that the installing contractor submit calculations on the valve base plate demonstrating that the bearing stress from the baseplate to the bearing pad is less than 12 psi. They cannot justify why they selected 12 psi, even after I...

I have a question about an application of a bearing pad. We have an application where a 24” ball valve in a pump station is mounted to a concrete pedestal. The ball valve is located “in-line” between a large pump and a pipe header distribution system. We are suppose to use a...
