高纯度TFM内衬
High Purity TFM Lined

特点 - CPVC
Features - CPVC

　　这种高技术TFM内衬蝶阀特别适用于要求高纯度和最高耐化学品特性的应用场合。美国斯毕尔公司独有的部件界面密封技术将阀瓣与所处理的流体介质完全隔离开来，只有内衬才会接触到流体介质。通径范围一般为DN50至DN150。
　　This advanced technology TFM Lined valve is specially designed and produced for applications requiring high purity and maximum chemical resistance. Spears® exclusive component-interface seal fully isolates process media to disc and liner contact only. Custom produced in sizes 2" through 6".

• 在ECTFE含氟聚合物阀瓣与TFM内衬之间的直接阀瓣-内衬密封结构能够实现积极有效的关闭效果。特殊设计的偏置阀瓣结构能够快速从密封表面提升起来，最大限度减小磨损并降低操作力矩。
  Direct disc-to-liner seal between ECTFE fluoropolymer disc and TFM liner for positive shut-off. Specially designed offset disc lifts quickly from sealing surface to minimize wear and reduce operating torque.
• 特殊的阀瓣-内衬界面结构将阀门部件与所处理的流体介质隔离开来，避免阀杆和弹性材料衬套的密封接触到所处理的流体介质。万一出现密封故障，泄漏就被排出外面，从而保护所处理流体介质的纯正性。TFM衬套作为内衬的一部分整体成型，从而将CPVC阀体隔离开来。
  Special disc-to-liner interface isolates valve components from process media. Eliminates stem and elastomer backing seal contact with process fluids. In the unlikely event of seal failure, leakage is expelled externally to protect process integrity. TFM skirt is integrally formed as part of the liner to isolate the CPVC body.
• 实心、完全隔离的316不锈钢阀杆，附加PTFE涂敷以增加安全保障。
  Solid, fully isolated type 316 stainless steel stem is additionally PTFE coated as a safeguard.
• 法兰结构，耐化学品和耐腐蚀的CPVC阀体配置整体成型的执行机构安装垫，可处理的流体介质温度可增加到93^oC。
  Lug style, chemical and corrosion resistant CPVC body features integrally molded actuation mounting pad and provides increased temperature handling capability to 200^oF.
• 316不锈钢法兰内嵌件便于迅速进行阀门的单侧安装，使得在系统中增加阀门变得容易。
  316 stainless steel Lug Inserts provide quick single-side valve installation and easy system add-on.
• 低高度的齿轮操作机构配置高效蜗轮驱动结构，并内置位置指示器和高强度抗冲击的聚丙烯手轮。操作机构外壳采用粉末涂层以改善清洁度。可反转特性使得操作时即可在右侧，也可在左侧。
  Low Profile Gear Operator features high efficiency worm gear drive with built-in position indicator and high impact polypropylene handwheel. Operator housing is powder coated for improved cleanliness. Reversible for either right or left side operation.
• 在水温23^oC条件下，最大内部压力等级为150 psi。
  150 psi Maximum Internal Pressure rating at 73^oF.
