Miller三通球阀介绍：

三通球阀有T型和L型。T型能使三条正交的管道相互联通和切断第三条通道，起分流、合流作用。L三通球阀型只能连接相互正交的两条管道，不能同时保持第三条管道的相互连通，只起分配作用。

L型流道的三通4面阀座球阀，采用2面阀座。主要用于流路的换向。

T型流道的三通4面阀座球阀，采用4面阀座，受力平衡，保证闭止通道上可靠密封。主要用于分流、混流、换向以及三通道的完全开放。

Three Way Ball ValvesSeries is a carbon and stainless steel ball valve that is a versatile small size (3/8" to 1-1/2") multiport ball valve. It consists of a heavy duty center section that can be furnished with bolted-on screwed ends for a valve rated to Class 400, or with flanged ends for either a Class 150 or Class 300 valve. It can also be furnished with bolted on socket or butt weld ends. All body gaskets are Teflon, eliminating concerns about elastomer compatibility with the operating fluid. The valve features four seats for equal seat loading. The unique live-loaded cup-and-cone lower primary stem seal-thrust bearing separates the dynamic bearing and static sealing functions. In addition, there is a multiple v-ring upper secondary stem seal.
