类型B蝶阀锁定手柄和刻度板
Model-B Butterfly Valve Locking Handle and Index Plate

　　这种组件，包括塑料刻度节流板和安装五金件可能被视为是一种替代手柄组件，因为它与在订购配置杠杆手柄的基本型阀门上安装的手柄是相同的总成。在手柄上有个孔，用做触发锁定操作的封锁点，因此，在关闭位置锁定阀门，或在6或7个开启度(DN80和DN100每个增量为15^o，而DN150每个增量为12.9^o)，包括全开位置上锁定阀门。手柄状态，与阀瓣状态完全一致，在任何时候都是可观察的。
　　This kit, which includes the plastic index throttling plate and mounting hardware may be thought of as a replacement handle kit, because it is the same subassembly that is mounted to the basic valve when it is ordered with a lever handle. A hole in the handle provides a blockage point for trigger lock operation, thus, locking the valve in the off position or any of the 6 or 7 increments of opening (15^o each for 3" and 4" valves or 12.9^o each for 6" valves), including the full on position. The handle position, aligned with the fully on disk posture, is visible at all times.

型号C蝶阀锁定手柄和刻度板
Model-C Butterfly Valve Locking Handle and Index Plate

　　在这种情况下，杠杆锁定手柄与金属刻度节流板分开销售。后者实际上是一个组件，包括安装五金件和位置锁定臂杆。位置锁定臂杆可以用来将手柄锁定在开启或关闭的位置，或者附着在臂杆上的翼形螺丝，可用作止动记忆装置，使得阀门可以重新开启到先前的位置上。手柄和刻度组件可以视为替换手柄组件，因为它与在订购时配置杠杆手柄的基本型阀门上的安装的手柄是相同的组件。手柄上的孔用作触发锁定操作的封锁点，因此，可以将阀门锁定在关闭位置，或者任何9个增量(每个增量为10^o)的开启度，包括全开位置上。不需要多余的锁定装置。手柄位置，与阀瓣的状态完全一致，在任何时候都是可观察到的。
　　In this case, the lever-lock handle is sold separately from the metal index throttling plate. The latter is actually a kit, which includes the mounting hardware and the position-lock arm. The position-lock arm may be used for locking the handle in the on or off positions or the thumb screw, which is attached to the arm, may be used as a memory stop, so the valve can be reopened to the previous position. The handle and index kit may be thought of as a replacement handle kit, because it is the same subassembly that is mounted to the basic valve when it is ordered with a lever handle. A hole in the handle provides a blockage point for trigger lock operation, thus, locking the valve in the off position or any of the 9 increments of opening (10^o each), including the fully on position. There are redundant on/off locking provisions. The handle position, aligned with the fully on disk posture, is visible at all times.

用于球阀的锚定手柄
Dead Man Handle for Ball Valves

　　通过克服弹簧的弹力来进行球阀的手工操作。翻开手柄后，弹簧的机械弹力促使手柄恢复到初始安全位置。这种组件可以指定为弹簧关闭或弹簧开启，以确保危险流体介质的的无过错操作。此外，这种组件可以在工厂里安装在新的阀门上，或者现场安装在现有的阀门上。组件里的安装托架与用于在Tru-Bloc阀门上安装执行机构的安装托架相同。
　　Provides for the manual operation of a ball valve by overcoming a spring. Upon release of the handle the mechanism is sprung to the original safe position. The kits may be specified as spring-to-close or spring-to-open to ensure unmistakable control of a hazardous medium. And, the kit may be mounted on a new valve in the factory or mounted on an existing valve in the field. The mounting brackets in the kits are the same as those used for mounting actuators on Tru-Bloc valves.
