Most cable systems on bikes only pull the device, a spring returns things to the original position. The dump valves depend on the stiff cable to push the blade shut, ever try pushing a rope? No lube is recommended. My thought is that there are many installations where the cable is bent too much, the specifications are in the installation manual. To add to the problem, "stuff" can flow into the area where the blade is pulled when the valve is anywhere but completely closed, IMO that is a design defect.
