手动齿轮操作机构(续) Manual Gear Operators (continued) |
旗形指示器选配件 Provides an easy visible indication of the relative disk position. Used when the valve is mounted in high or out-of-reach locations, but frequent monitoring of the valve position is required. |
2英寸方形操作螺母选配件 Replaces the handwheel on gear operators when a standard utility wrench is to be used for valve operation. The most common application is for valves located in an underground valve box. |
|
挂锁法兰(铸铁)选配件 Provides eight positions whereby a keyed or combination padlock can be used to lock the gear operator into position to prevent accidental or deliberate tampering with valve posture. |
止动记忆选配件 Provides infinite position memory at any position throughout the 90o arc of rotation. Allows for valve closing and reopening to previously balanced position. |
链条垂下操作机构选配件 The Babbit Sprocket Rim (cast iron) with chain guide (malleable iron) and 1/0 drive chain allows remote operation of a gear operated valve mounted overhead in out-of-reach locations. The total footage in the loop of chain must be stipulated. |
用于安装在Tru-Bloc球阀上的齿轮操作机构组件 Provides mechanical advantage for higher turning torque of larger size valves (1-1/4" – 6"), prevents sudden opening or closing of a ball valve, and presents the opportunity for the same precise control of valve position afforded by multi-turn valves. A TB Ball Valve-Mount Kit is not required for adapting a gear operator to the external top bearing plate of a stem extension for a ball valve. | ||
