Product Features:
1.Cryogenic Environment Design: Cryogenic butterfly valves are made of special materials and can operate stably under extremely cryogenic conditions, ensuring the reliability and durability of the valve in extremely cold working conditions. Its structural design fully considers the thermal expansion and contraction effects in low temperature environments, ensuring that the valve can maintain good sealing and operating performance in the process of temperature changes.
2.Compact and Lightweight Structure: With its unique structural design, the cryogenic butterfly valve has the advantages of compact structure, small size and light weight, which greatly reduces the use of raw materials. It requires small installation space, which is convenient for flexible arrangement in various pipe systems.
3.Excellent Sealing Performance: The cryogenic butterfly valve adopts advanced sealing technology to ensure the excellent sealing performance under low-temperature environments. Its sealing material has been specially treated to resist the shrinkage and hardening of the material caused by low temperature, thereby ensuring the long-term stability of the sealing effect.
4.High-strength Valve Seat and Durability: The valve seat adopts throughout shaft structure and has excellent comprehensive physical properties, corrosion resistance and wear resistance after careful heat treatment. In the process of opening and closing the butterfly valve, the valve seat only rotates, avoiding the lifting action to the damage of the packing, ensuring the reliability of the sealing, further extending the service life.
5.Various Top Flange and Actuators Types: Low temperature butterfly valves provide multiple interface modes such as wafer connection, butt welding connection and lug wafer connection to meet the needs of different pipeline systems. At the same time, it is equipped with manual, worm gear transmission system, electric, pneumatic, hydraulic and hydraulic linkage actuator options, supporting long-distance operation and automation technology operation, improving the flexibility and intelligence level of the system.
6.Wide Medium Adaptation: In addition to being suitable for cryogenic gases, cryogenic butterfly valves also have good adaptability and are suitable for a variety of cryogenic liquid medium including liquefied natural gas (LNG), liquid oxygen, liquid nitrogen, etc., ensuring stable operation under various cryogenic conditions.
7.Fugitive Emission Test: Valves packing in shaft area adopts complex sealing sets to guarantee no leakage under cryogenic conditions. Shaft area design confirm to ISO 15848-1 type test and API 641 fugitive emission tests.
