Notes:
- All are single-seat valves.
- The PPD25 type pressure relief valve should be installed in horizontal pipes.
- The 67R type pressure relief valve is also manufactured for high-pressure gas equipment certification.
- The flanged type of the 67R and PPD25 models are also manufactured in ASME Class 150 and 300.
