聚丙烯Tru-Bloc球阀 True Union黑和Chem-Pure® (天然) Polypropylene Tru-Bloc Ball Valves True Union Black and Chem-Pure® (Natural) 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 黑聚丙烯 Black Polypropylene 　　紫外线会使PP材料严重老化。因此，所有PP管道产品，包括阀门，Chemtrol制造的用于通用化工领域的产品，包含最少2.5%碳黑。由于采用非常高浓度的黑色素，有效地起到掩蔽的作用，因此Chemtrol管道系统可以长期安装在直接暴露在阳光下的地方。 　　Ultraviolet radiation produces severe degradation of PP. Therefore, all PP piping products, including valves, which Chemtrol produces for general chemical service, contain a minimum of 2.5% carbon black. By virtue of the masking effect by the unusually high concentration of black pigmentation, a Chemtrol piping system may be installed for long-term service with exposure to direct sunlight. Chem-Pure (天然)聚丙烯 Chem-Pure (Natural) Polypropylene 　　在我们的Chem-Pure管道产品系统中，用来制造所有部件的材料都是PP材料，这是因为PP材料所含的金属成分、天然纯丙烯以外的有机成分和自由离子的含量很低。在塑料树脂内，没有添加颜料或其它掺杂物(天然)。Chem-Pure系统适用于高纯度化工行业或无离子水。 　　The PP material utilized to produce all of the components in our Chem-Pure piping products system was selected because of its extremely low content of metals, organic compounds other than naturally pure propylene, and free ions. No pigments or other adulterants (natural) are added to the plastic resin. Chem-Pure systems are intended for high purity chemicals or DI water. 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。这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，不需要改变管道长度。 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. This permits fouled valve replacement with a new body cartridge, which will fit the old union nuts. No change in piping length is required. 型号C结构特点，在于阀门两端的TFE阀座，确保阀座后侧周围没有泄漏。在Chemtrol Tru-Bloc关闭阀安装和测试后，连接到满储的储罐的管道开口将不会开始滴漏。 Model-C design features, under the TFE seats at both ends of the valve, ensure no leakage around the back-side of the seats. Open piping attached to a filled tank will not start to drip-leak following installation and test of a Chemtrol Tru-Bloc shut-off valve.

型号C结构，在阀座支架下配置增能器O形环，使得阀门能够根据阀座磨损状况自动进行调整。在工厂组装期间，阀座的封装挤压和阀门测试的调整都是通过机械设备进行操作。一旦安装完毕，手动旋紧的管接螺母就紧压着Chemtrol阀门的密封面。 Model-C design, with an energizer O-ring beneath the seat-carrier, enables the valve to automatically adjust for seat wear. Adjustments for envelope squeeze on seats and valve testing are done by machine during factory assembly. Upon installation, a hand-tightened union nut serves to compress the face-seal of a Chemtrol valve. 全端口(全流道)结构对流体的阻力最小，因此压降也最小。 Full port design produces minimum flow restriction with the lowest possible pressure-drop. 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. 特别的红色手柄能够远距离表示“启闭”和流向。手柄上模铸的箭头表示旋转方向，方便操作人员在90o角度范围内进行操作。由于实际应用中可能需要拆卸手柄，因此D形环阀杆平面表示“启闭”，阀杆顶部的的模铸箭头表示流向。 Distinctive red handle indicates “open/close” and direction of flow at a distance. And molded-in arrows on top of the handle dictate rotational direction to personnel for easy operation within 90o stops. For applications requiring handle removal, the D-ring stem flats indicate “open/close” and a molded-in arrow on top of the stem indicates flow direction. 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和塑料安装组件。 Refer to the Chemtrol Valve Actuation Guide for full selection of electrical and pneumatic actuators with accessories, including plastic housings and plastic mounting kits for field or factory assembly to valves. 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.
