PVC角形和Y形阀门 PVC Angle and Y-Pattern 22oC温度下压力为150 psi，非冲击性水 150 psi at 73°F water–non-shock Chemtrol型号 T45AC-V Chemtrol Figure No. T45AC-V Chemtrol型号 T45YP-V Chemtrol Figure No. T45YP-V 两种类型都只有 螺纹端口连接件 可供 Both styles available with threaded end connections only. 　　Chemtrol截止阀具有两种类型，角形和Y形，可以在任何所给通径的阀门范围内使用可互换部件。只有阀体是不相同的。Y形压降最小，即使与通用的直立式截止阀比较也是如此。因此，这种阀门对于启闭和节流双重应用的场合是很好的选择。 　　Both styles of Chemtrol Globe Valves, the angle and the Y-pattern, utilize interchangeable components within any given valve size. Only the bodies are different. The Y-pattern style has a minimal pressure-drop, even when compared with a conventional upright style globe valve. Therefore, it is an excellent choice for combination on-off and throttling applications. 　　Chemtrol角阀适用于需要高压降的场合。这种阀门最主要的应用之一是作为泵的旁路控制阀。 　　The Chemtrol Angle Valve is used where a higher pressure-drop is desirable. One of its more common applications is as a pump by-pass control valve. 特点 Features 具有韧性的玻璃强化聚四氟乙烯(Teflon)阀座阀瓣确保长期的正作用密封。 Malleable glass reinforced PTFE (Teflon) seat disk ensures long-lasting positive sealing. 阀杆上的短梯形螺纹适用于快速启闭操作。 Stub acme thread on stem provides rapid open-close operation. 液体或泥浆绝对不会接触阀杆螺纹。 Liquid or slurry never touches stem threads. 可用作流体流量的启闭和节流控制。 Can be used for both on-off and throttling control of fluid flow. 易于在线维护。 Easy in-line maintenance.
