　　美国斯毕尔公司T形“零死角”隔膜阀结构将阀门和直接分流的T形管件整合在一起，对于架空引入管线和其他连接到循环回路的管线，因此不再需要T形和缩径管件。这种T形阀门连接更坚固也更紧凑，非常有利于所处理流体介质在关键部位的节流、取样、排放或转向。这种“零死角”结构特别适用于无离子水和其他关键应用场合。由于阀门特别接近主管道，因此能够最大限度减少流体介质滞留区域，消除可能贮存滋生细菌和其他污染物的“死角”。根据订购可以提供套管、承插和螺纹或特别加固（SR）螺纹连接端口的阀门，通径从DN15至DN50，并且定制T形承插连接口径以便与主管道连接口径相匹配。
　　Spears® Tee-Style "Zero-Dead-Leg" Diaphragm Valve design integrates valve and Tee-fitting for direct branch take-off and eliminates the need for tees and reducing fittings normally required for service drops and other tie-ins to the loop. The Tee-Style Valve provides a stronger, more compact connection enabling throttling, sampling, draining or diverting of critical process fluids. The "Zero Dead-leg" design is excellent for DI water and other critical applications. Close proximity of valve to mainline minimizes any areas of fluid stagnation by eliminating "dead leg" that can harbor bacterial growth and other contamination. Produced to order with Spigot, Socket & Threaded, or Special Reinforced (SR) Threaded end connection valve sizes ¹/₂" through 2", and specified Tee Socket connection sizes for virtually any mainline connection size.
