PVC和CPVC三通球阀 True Union三位(多通阀)和二位(分流阀) PVC & CPVC 3-Way Ball Valves, True Union 3-Position (Multiport) and 2-Position (Diverter) 22oC温度下压力为150 psi，非冲击性水，全端口(全流道) 150 psi at 73oF water–non-shock–full port Chemtrol True Union多通阀是三向/三位球阀 The Chemtrol True Union Multiport Valve is a 3-Way/3-Position Ball Valve 　　这种球阀特别适合需要控制流向和启闭的应用场合。当手柄旋转到180o，三(3)位启、闭、启，将中心流入的流体介质转向到一侧出口处(在0o位置)，然后关闭(在90o位置)，然后对面出口位置(在180o位置)。多通阀球阀也可用于从两侧的流进端口转向到中心出口分支上，采用的是中部位置关闭的方式(此时手柄垂直于阀体)。在180o之间的任何位置，两个流进的流体介质都避免了交叉污染。 　　It is ideally suited for applications where flow direction and on-off control are needed. When the handle is rotated 180o, the three (3) positions of on, off, and on may direct flow from the branch center-inlet to one side runoutlet (at the 0o stop position), then to shut-off (at the 90o position), and then to the opposite side run-outlet (at the 180o stop position). The multiport may also be used to alternately direct flow from either of the side run-inlet ports to the branch center-outlet port, with shut-off at the midposition (when handle is perpendicular to the body). Cross-contamination of the two inlet streams is prevented at all intermediate positions between the 180o stops. Chemtrol True Union分流阀(转向阀)是一种三通/二位球阀 The Chemtrol True Union Diverter Valve is a 3-Way/2-Position Ball Valve 　　这种阀门用于要求在90度角内实现流向的转向或分流，但是不需要实现关闭的应用场合。当手柄旋转90o时，两个位置的开启能够将流体从分支中心进口转向到一侧的出口(在0o位置)，然后转到反向出口(在90o位置)。这种分流阀(转向阀)也可以用来将两个侧面进口的流体转向到分支中心进口端口。分流阀的中间端口并没有关闭的作用。因此，这种阀门在90o角度内的任何中间位置可以用作比例混合阀使用。 　　It is used for applications where a quarter-turn will achieve diversion of flow, but shut-off control is not required. When the handle is rotated 90o, the two positions of on and on may direct flow from the branch center-inlet to one side run-outlet (at the 0o stop position), and then to the opposite side run-outlet (at the 90o stop position). The diverter may also be used to alternately divert flow from either of the side run-inlet ports to the branch center-inlet port. The internal porting of the diverter makes no provision for shut-off. Therefore, the valve can be used for proportional mixing at all intermediate positions between the 90o stops. 特点 Features 这种阀门问世30多年来，其阀体长度和管套接连接件上的强力改进顶点螺纹始终没有改变。因此，这种True Union结构使得人们可以用新的阀腔更换肮脏的阀门，新旧管接螺母能够互相配合，好像永久性连接着邻近的管道上。不需要破坏或改变管道长度。 The laying length of the body and the heavy-duty modified-acme threads in the union connections to the body have not changed in the 30-year history of the valve. Thus, the True Union design permits the replacement of a fouled valve with a new body cartridge, which will fit the old union nuts that are likely to be permanently attached to adjacent piping. No disruption or length change of connected piping is required.

(流向)模铸在阀体的外部，表示配置TFE阀座的固定端口。当断开邻近的管道进行维修或更换时，可能需要堵塞这个端口的流体。 FLOW externally molded onto the body to indicate the fixed end containing a TFE seat. Flow can be blocked at this port while adjacent piping is disconnected for repair or alteration. (调整)模铸在阀体的外部，表示用于组装的开口端口。这种管接螺母的调整能够弥补TFE阀座的磨损，避免由于拆卸阀门进行内部调整作带来的损失。 ADJ externally molded onto the body to indicate the open end used for assembly. Adjustment of this union nut can compensate for wear of TFE seats, with no production loss to remove valve for internal adjustment. 这些阀门都是在没有硅酮成分的环境下制造和组装的。 Valves are manufactured and assembled without exposure to silicone compounds. 使用90o端口时，全端口(全流道)结构将流体阻力和可能的压降减少到最小程度。 Full port design produces minimum flow restriction with the lowest possible pressure drop for 90o porting. 参阅Chemtrol阀门执行机构指南，选择电动或气动执行机构及附件，包括用于阀门现场安装或工厂组装的塑料外壳。 Refer to the Chemtrol Valve Actuation Guide for a full selection of electrical and pneumatic actuators with accessories, including plastic housings. 注意： Notes 　　参阅第2页的“部件材料清单”。如果需要了解更多的材料选择，请参阅第1页的“材料”。适用于球阀的“执行机构安装参数”和“备选附件”的完整清单请参阅第21页及以后的内容。这些阀门的“安装和维护指南”内容在第8页。如果需要额定压力-温度的特殊关系，请参阅第33页的“工程技术参数”。如果需要“Chemtrol阀门标准”，请参阅第35页。 　　See page 2 for a list of Components and Construction Materials.
