When pressure vessels or pressure-bearing systems lack effective protection and the pressure exceeds the specified value, catastrophic safety accidents may occur, posing serious risks to plant equipment and operating personnel.

As a core safety protection device for overpressure relief, a safety valve automatically opens when the medium pressure inside equipment or pipelines rises abnormally. It quickly releases pressure to prevent accidents such as explosions and leakage caused by system overpressure, effectively protecting equipment safety and personnel safety.

BasCo safety valves are designed in accordance with international and domestic standards such as API 526, API 520, ASME XIII, GB/T 12243, GB/T12241-2021, and GB/T12242-2021. They have obtained qualification certificates including TS, EAC, and type test certificates. The product range covers four major series: compact type, closed type, pilot-operated type, and open type. With complete nominal diameter specifications, they can meet overpressure relief requirements under various operating conditions involving gas, steam, liquid, and other media. Each safety valve undergoes at least one inspection before delivery to ensure product quality and stable, reliable operation.

BasCo 4500 series pilot-operated safety valves adopt a non-flowing design, meaning no system medium flows through the pilot valve during the pressure relief cycle. This design minimizes the risk of freezing in wet fluids and prevents particles from entering the pilot valve, ensuring long-term stable valve operation.

BasCo safety valves are used to protect personnel and the environment, with applications in petroleum, chemical, power plant, pharmaceutical, and food industries.
