Single screw on dump valve won’t…
The single screw that is suppose to grip the outer cover of the cable and hold it tears away and then the valve won’t shut. What can a guy to to ensure it holds it?

Sounds like a pretty poor design, The Valtera valve I posted seems to be about all I can find for reference and does have a pretty healthy looking clamping system.
Depending on one single screw to put pressure on the jacket to hold the jacket in place will never work for long as you have found out. You need a clamping system that puts pressure on the jacket 360 degrees (your hose clamp setup would be a improvement on a single point of contact).
You can rig up a bunch of different clamping systems that rely on one single point of contact (IE screw into the jacket) on what you have and it will keep failing.
This is the same idea as what you typically find on small engine cable throttles on lawn mowers, they always provide a healthy clamping system to hold the outer jacket from moving that doesn't use a single screw into the jacket..
Not a real good example but here is a pix that may illustrate a bit better..
In the case of this design the outer jacket is clamped between two points without crushing the jacket. The other end goes to the throttle and there is a metal clamp that surrounds the jacket to hold it in place.
If you really want to keep the valve you have, you will need to rig up a permanent metal bracket and clamping system that is capable of surrounding the jacket and attach the bracket to your valve some how.
Otherwise, perhaps bite the bullet and replace with a Valtera valve design like I showed and be done with the mess.
