These multi-turn valves are designed for accurate flow control, outstanding durability, and leak-proof operation. The absence of stagnation pockets or crevices, together with the self-cleansing of unobstructed flow through the valves, make them ideal for slurries, salts which tend to plate-out on surfaces, and services which are sensitive to microbiological growth. 特点 Features 隔膜将阀门的工作部件与所处理的流体介质隔离开来，延长了使用寿命，改善了防泄漏性能。 Diaphragm isolates the working parts of the valve from process medium for long life and leak-proof performance. 无填料设计将外壳泄漏的可能性降到最小程度，特别适用于排放控制应用领域。 Pack-less design minimizes the potential of shell leakage for ideal emissions control. 弹性隔膜确保流体的气密性关闭。 The resilient diaphragm assures bubble-tight closure to flow. 没有空穴或死角，因此避免了累积，所处理的流体的滞流，或污染。 No pockets or dead spaces, thus preventing accumulation or stagnation of process fluids or contaminants. 多旋转操作使得手动阀门能够进行精确节流。 Multi-turn operation allows for precise throttling of manual valves. 可视位置指示器是标准配置。 A visual position indicator is standard. 三元乙丙橡胶或聚四氟乙烯隔膜选项使得应用更加广泛，从防腐，到泥浆和高纯度。 EPDM or PTFE diaphragm selection affords wide range of applications, from corrosives to slurries and high-purity. 固定器/支架螺栓孔位于阀门的基座。 Anchor/support bolt holes are located in base of body. 注意： Notes 　　如果需要了解“部件和结构材料清单”，请参阅第14页。如果需要更深入地了解材料选项，请参阅第1页的“材料”。需要了解压力与温度之间的特定关系，请参阅第33页的“工程技术参数”。需要了解“Chemtrol阀门的标准”，请参阅第35页。 　　See page 14 for a list of Components and Construction Materials.

However, they can be field fabricated by purchasing an EPDM diaphragm for replacement in a PTFE trimmed valve. 在制造期间，阀体上的法兰的隔膜密封表面可以进行特别的预制，以强化聚四氟乙烯隔膜的密封性能。对于配置橡胶隔膜的阀体并进行这道最后的工序。因此，聚四氟乙烯隔膜无法替换配置三元乙丙橡胶阀内件的阀门。 At the point of manufacture, the diaphragm sealing surface of the flange on the valve body receives special preparation to enhance sealing with PTFE diaphragms. This finishing operation is not performed on bodies receiving rubber diaphragms. Therefore, a PTFE diaphragm cannot be used as a replacement in an EPDM trimmed valve. 所有PVC和CPVC阀门和DN80和DN100的NPP和NPVDF阀门都有IPS (US)插口。这些阀门类型可以采用任何相同口径和材料的标准Chemtrol连接件进行现场连接，利用液状粘固剂或专门的Chemtrol热熔设备-材料。通径DN15 - DN50的NPP和NPVDF阀门具有公制插口。工厂生产的这种材料和通径的法兰和承插类阀门需要利用特殊的、配置公制承插口的组装公制连接热面和连接件。由于这些必需的项目在销售时并不提供，因此不建议购买这些材料和通径的插口类型用于现场连接。 All PVC and CPVC valves and 3" & 4" NPP and NPVDF valves have IPS (US) spigots. These valve styles can be field joined with any standard Chemtrol fitting of the same size and material, utilizing solvent cement or Chemtrol heat fusion equipment–material specific. NPP and NPVDF valves in sizes 1/2" - 2" have metric spigots. Factory produced flanged and socket styles in these materials and sizes utilize specially fabricated metric joining heat faces and fittings with metric sockets. Since these essential items are not offered for sale, purchase of spigot styles in these materials and sizes for field joining is not encouraged.
