CPVC/PVC蝶阀 - 型号B CPVC/PVC Butterfly Valves–Model-B DN100和DN150蝶阀的阀体、阀瓣/阀杆和节流板是PVC。DN80蝶阀的部件是CPVC。 22oC温度下压力为150 psi，非冲击性水(DN150为115 psi) 4" & 6" Body, Disk/Stem and Throttle Plate are PVC. 3" components are CPVC. 150 psi at 73oF water–non-shock (6" size 115 psi) 　　型号B是适用于化工领域的最好的蝶阀。阀瓣和阀杆护层都是模压在316不锈钢六角轴上形成一件式组合结构，使得金属轴从头到尾暴露在流体介质中变得不可能。上部和下部的TFE轴承衬套经过硬化，在保护层模压时嵌入到阀座/护层内，从而使得护层和衬套之间的泄漏变得不可能。双重O形环密封槽经过机加工嵌入在保护塑料的阀杆护层内，防止多余的阀杆泄漏进入上部和下部衬套地连接位置中。由于这些阀杆密封支撑靠着TFE衬套旋转，所以显示这些密封外部磨损导致的阀门外壳泄漏实际上就没有再发生。 　　The Model-B is the best butterfly valve for chemical applications. The disk and stem sheath are molded over a 316 stainless hex shaft to make a one-piece assembly, making it impossible for the metal shaft to be ex-posed to the fluid medium over its full length of top and bottom stem. The upper and lower TFE bearing-bushings are vulcanized to the seat/boot as the boot is molded, making leakage between the boot and bushings impossible. The grooves for double Oring seals are machined in the stem sheath of protective plastic for redundant stem leakage protection in conjunction with both the upper and lower bushings. Since these back-up stem seals rotate against the TFE bushings, valve shell leakage, indicating wear on the outside of these seals, is virtually unreported. 特点 Features 可配置在符合下列标准的法兰之间：ANSI B 16.5, 150磅级；ISO 2084 PN 10, DN80；和DIN 2532, PN 10, DN80. DN80通径具有4螺栓和8螺栓两种模式。 Mates between ANSI B 16.5, Class 150; ISO 2084 PN 10, DN 80; and DIN 2532, PN 10, DN 80. Both 4-bolt and 8-bolt patterns are in 3" size. 设计独特的“干燥轴密封” - 液体绝对不会接触到轴。 Unique "dry shaft seal" – liquid never contacts shaft. 顶部轴承，以及上部轴承和底部轴承，是玻璃纤维填充TFE材料，用于使得操作更加容易，并最大限度延长使用寿命。 Top bearing, as well as the upper and lower bushings, are glass-filled TFE for ease of operation and maximum service life. 阀座/护层结构消除了对接法兰之间的密封垫的需求。 Seat/boot design eliminates need for gaskets between mating flanges. 选择FPM或EPDM阀座和密封，以满足耐多种化学物质/水服饰的应用要求。配置FPM阀内件的阀门，已经成功应用于氯消毒和漂白剂喷射等领域。 Selection of FPM or EPDM seat and seals offers resistance to diverse chemical/water applications. With FPM trim, valves have been notably successful in the disinfection services of chlorine and bleach injection. 可提供用于过高或地下系统的人工操作，以及其它特殊需要的附件。请参阅第24页。 Valve accessories for manual operation in overhead or underground systems and other special needs are available.
