2英寸方形螺母阀杆接合器–使得阀门可以采用标准通用(AWWA)的扳手来操作阀门。最常见的应用是用于位于地下阀门盒内的阀门操作。用于球阀的方形螺母由PVC制成。它夹在阀杆上，并且锁在槽内，用于任何材料球阀的旋转止动，代替其标准手柄。 　　2" Square Nut Stem Adapter–Permits operation of a valve with a standard utility (AWWA) wrench. The most common application is for valves located in an underground valve box. The square nut for ball valves is made from PVC. It snaps onto the stem and locks into the slot for turning-stops of a ball valve of any material, in place of its standard handle.

圆形安全手柄–这种结构用于防止由于人员服装或设备绊住水平手柄导致的低扭矩阀门的操作故障。 　　Round Safety Handle–Design prevents accidental operation of low-torque ball valve by snagging the lever handle with personal clothing or equipment.

用于球阀的远距离阀杆加长装置–使得阀杆具有操作空间，配置整体的旋转止动装置，用于隔热绝缘，面板安装，或较浅的水下应用。这些加长装置由实心PVC材料制作，而且比较短；所以不需要配置顶部支撑。虽然价格是根据受并与阀杆之间的每英寸距离制定的，但是如果在订购时特别要求，也可以按照准确的尺寸制作。如果加长装置安装在与PVC或CPVC不同的其它材料阀门上，在订购时也必须特别指定。 　　Standoff Stem Extensions for Ball Valves–Provide handle clearance, with the integrity of turning-stops, for insulating, panel-mounting, or shallow submerged applications. These extensions are made of solid PVC, and are short; so top support is not required. Although priced in increments of 1" standoff, between handle and stem, they can be supplied in exact lengths if specified when ordered. And, if the extension is to be installed on a valve of material other than PVC or CPVC, that must also be specified when ordering.
