Too often you need to operate valves that are in a very inconvenient position: too high, too low, in a toxic environment, under a tank, outside your reach, underwater, and so on.
What could be the solution to make it more convenient? Replacing the valve? No, not likely. This is expensive and time consuming, and the process need to be stopped.
The answer is a heavy-duty flexible shaft system. This flexible shaft instantly places the handwheel of the lever in the best ergonomic and safe position: above water, at a proper height, and outside dangerous areas.
These flexible shaft systems are able to supply an output torque of 1000nm.
If you want to help your operators, be flexible.
