低温气动球阀产品概述

低温气动球阀是专为低温环境设计的气动控制阀门，通过压缩空气驱动执行器带动球体旋转，实现管路系统中低温介质的通断及流量控制。以下是其产品概述：

 低温气动球阀- 工作原理：利用压缩空气推动气动执行器内的活塞或叶片运动，进而带动阀杆和球体旋转90度。当球体通孔与管道通道对齐时，阀门开启，低温介质流通；旋转90度后，通孔与通道错开，球体与阀座紧密贴合，阻断介质流动。

低温气动球阀- 结构特点：阀体、球体等核心部件多采用低温钢（如304、316不锈钢）等耐低温材料，避免低温下材料脆化。密封结构常采用耐低温密封件（如聚四氟乙烯或特殊合金），确保低温下的密封性能。整体结构紧凑，配备气动执行器，响应速度快。

低温气动球阀- 产品优势：耐低温性能好，可在-40℃至更低温度环境下稳定工作；气动驱动方式操作便捷，易于实现远程自动化控制；开关迅速，密封稳定，能有效防止低温介质泄漏；流阻小，流通效率高，适合低温液体、气体等介质的输送控制。

低温气动球阀- 应用领域：广泛应用于天然气液化、低温制冷、冷链物流、空分设备等行业，用于控制液氮、液化天然气（LNG）、低温丙烷等低温介质的输送。

Low-temperature pneumatic ball valve is a pneumatically controlled valve designed specifically for low-temperature environments. It drives the actuator through compressed air to rotate the ball, realizing the on-off flow control of low-temperature media in pipeline systems. The following is its product overview:

 Low-temperature pneumatic ball- Working principle: Compressed air is used to push the piston vane in the pneumatic actuator to move, which in turn drives the valve stem ball to rotate 90 degrees. When the through-hole of the ball is aligned with the pipeline channel, the valve opens low-temperature media flows; after rotating 90 degrees, the through-hole is staggered the channel, the ball fits closely with the valve seat to block the flow of media.

Low-temperature pneumatic ball- Structural features: Core components such as valve body ball are mostly made of low-temperature resistant materials like cryogenic steel (e.g., 304, 316 stainless steel) to avoid material embrittlement at low temperatures. The sealing structure often uses low-temperature resistant seals (such as polytetrafluoroethylene special alloys) to ensure sealing performance at low temperatures. The overall structure is compact, equipped with a pneumatic actuator, has a fast response speed.

Low-temperature pneumatic ball- Product advantages: It has excellent low-temperature resistance can work stably in environments -40℃ to lower temperatures; the pneumatic drive mode is easy to operate facilitates remote automatic control; it switches quickly with reliable sealing, which can effectively prevent leakage of low-temperature media; it has small flow resistance high circulation efficiency, suitable for conveying controlling low-temperature liquids, gases other media.

- Application fields: Widely used in industries such as natural gas liquefaction, low-temperature refrigeration, cold chain logistics, air separation equipment, for controlling the transportation of low-temperature media such as liquid nitrogen, liquefied natural gas (LNG), low-temperature propane.
