气动低温三通调节阀产品概述
       气动薄膜（小流量、单座、双座）低温调节阀是气动薄膜（小流量、单座、双座）调节阀的变形产品，适合于低温（-250℃）状态下工作。它由气动薄膜执行机构和带长颈接管的阀体组件组成，长颈接管的作用是使阀杆密封处接近常温下工作，并减少外界热量传入。为减少热传递，长颈上盖采用薄壁结构。
优化考虑
       对于－100℃以上的低温阀，可以不用长颈型结构（内装四氟填料，其工作温度必须大于－30℃，故用长颈上盖，使之远离低温），使阀的高度大为降低。
气动低温三通调节阀主要技术参数

注：工作温度，公称通径，公称压力超出列表范围的产品，可与本公司商洽解决。
主要技术性能指标
      泄 漏 率：单座阀、小流量阀小于阀额定容量的10－4
                     双座阀小于阀额定容量的5×10－3
      回      差：带定位器，小于全行程的 3%
      基本误差：带定位器，小于全行程的±3%      
   注：采用标准的V型聚四氟乙烯填料
