AST designs and manufactures customized valves for oil and gas operations. These valves perform under high pressure, extreme temperatures, and corrosive fluids.
Since the 1980s, AST has supplied tailor-made valves for severe service. Our growth comes from close collaboration with clients and solutions that meet specific plant needs.
We use advanced design software and partner with leading R&D centers to test and validate each product. This ensures durability and safety in the most demanding environments.
AST supplies valves designed according to licensor specifications. We offer models with SIL certification, approved for safety instrumented systems. Our valves can be built from solid blocks of special alloys, such as Hastelloy or Urea Grade 316L stainless steel. Depending on the process, valves can include flushing nozzles or jackets to maintain flow and integrity.
We also perform advanced tests, including steam testing, fugitive emissions tests (ISO 15848, high and low temperature), cryogenic testing, and high-pressure gas testing up to 20,000 psi.
