Accreditation
We at Rockwood Swendeman are proud of the products and services we provide to our customers. Our facility is ASME and TUV accredited and we manufacture our valves to the specifications of the globally accepted ASME and Merkblatt codes. Our valves also conform with the Compressed Gas Association's specifications.

Service
We clean and package ALL of our valves for use in the oxygen service in compliance with the Compressed Gas Associations specification G-4.1. In addition we do not charge any extra fees for this level of cleanliness.

Setting Standards
Unlike most safety relief valve manufacturers, we are one of the few companies that produce valves for use in cryogenic temperatures, meaning the valves can withstand temperatures of -150 to +400 degrees Farenheit.
