API 609 Certification: Manufacturing Excellence Aligned with International Standards

• Our butterfly valve designs comply with API 609 technical requirements across multiple aspects, including structural strength, sealing performance, pressure resistance, and operating torque. This demonstrates our professional expertise in fluid control design and our internationally synchronized R&D capabilities.

• In the international engineering market, API 609 certification is often a basic qualification requirement set by energy and petrochemical industry owners. Achieving this certification means we possess the technical threshold and supply qualifications to compete for major international projects, securing our entry pass to the global bidding market.

• For us, what leaves our factory is not merely a valve, but long-term performance, operational safety, and brand trust. We value the quality of every delivery, ensuring customers can choose our products with confidence and peace of mind.

• API 609 defines strict requirements for design validation, materials, testing, and documentation. Our systems fully comply, as verified by rigorous third-party audits.

• Certification represents more than compliance – it's an endorsement of our capabilities. It provides us with differentiated advantages in a highly competitive market and becomes one of the key reasons customers prioritize our solutions.

 

• Our engineering team designs every butterfly valve body and sealing mechanism according to API requirements, submitting design drawings and compliance documentation for third-party review and approval.

• Our facility possesses precision machining, welding, and surface treatment capabilities, undergoing on-site audits and process consistency reviews to ensure every product batch meets specifications.

• We have further integrated our ISO 9001 quality management system with API process controls, ensuring traceability from raw material receipt to final inspection.

• Every valve undergoes pneumatic, hydrostatic pressure, torque, and low-pressure seal testing, with documented reports serving as audit evidence.

•  Throughout the certification process, we partnered with impartial organizations such as TÜV and SGS for third-party witnessing of critical tests, ensuring objective and authoritative validation processes.

• In high-temperature, high-pressure environments with corrosive or flammable gases, our butterfly valves maintain stable sealing and operational performance, effectively reducing leakage and explosion risks while meeting multi-national safety standards.

• Validated through pneumatic and torque testing, our products maintain smooth opening/closing and reliable sealing under extreme temperature differentials and rapid pressure changes, ensuring smooth and reliable operation.

• Valve designs resist water hammer impact and thermal expansion effects, reducing pipeline fatigue, extending service life, and minimizing unplanned shutdowns.

• Products utilize food and pharmaceutical-grade sanitary materials and internal surface treatments, balancing pneumatic sealing, corrosion resistance, and contamination-free requirements for cleanroom and sterile environments.

• Capable of withstanding challenges from strong vibrations, high dust, and high-pressure media, with valve seats and actuating structures featuring durability and high cycle life for long-term stable operation.
