Abstract
A diaphragm assembly for a pressure relief valve can include a disc guide that is configured to receive a portion of a disc holder, a bonnet adapter, and a diaphragm that is clamped at an outer edge between the disc guide and the bonnet adapter. The diaphragm assembly can be positioned between a bonnet of the pressure relief valve and a valve body of the pressure relief valve to convert the pressure relief valve to a backpressure-balanced pressure relief valve by counterbalancing a backpressure that acts upon the disc holder.
