| 1) | Supriya Spur Gear Boxes are known for the flexibility in customization for any ratio requirement. Gear Ratio and mechanical advantage plays a vital role in critically sizing the optimum size electric actuator thereby reducing the cost. |
| 2) | Gear boxes are compatible to AWWA C504, CE marked (Machinery Directive), API6D (Suitable) and IP68, IP67 Ingress Protection. |
| 3) | Supriya Gear Box is modular and can be fitted with tandem Spur Gear Box to achieve intended ratio. |
| 4) | Gear Box can also be provided with removable splined bushings between the gear drive and the valve shaft. |
| 5) | Twin Speed/Shaft gear box is available for reduced operating time by switching to lower ratio and thus higher mechanical advantage after unseating the valve. |
| 6) | Special arrangement with bevel gear mounted on the spur gear box can be provided to change the direction of handwheel rotation. |
