The ATKL series cryogenic ball valve is specifically engineered for extreme low-temperature environments, widely applied in petrochemical and industrial cryogenic systems. The valve body utilizes an investment casting process, achieving both high precision and structural strength. Its extended stuffing box design effectively isolates low-temperature thermal conduction, while the integrated anti-surge pressure relief mechanism ensures stable ultra-low-temperature sealing and prevents pressure instability risks. Core components undergo cryogenic treatment and ultra-low temperature testing, demonstrating exceptional resistance to brittleness and fatigue. Combined with anti-static and fire-safe structural design, it meets stringent safety standards for high-risk environments. Featuring an ISO 5211 standard mounting platform, it supports multiple actuation methods including manual lever, worm gear, pneumatic, or electric operation, with highly adaptable flange connections. The modular design balances flexibility with ease of maintenance, making it a dependable solution for critical applications through superior sealing performance, broad temperature adaptability, and multi-layered safety protections.
