As you see in the attached picture, The whole control set is hooked up from the discharge line of the compressor and this system has been working from 1970 without any problems!
I expected -at least- the elbow closed to the hanger had a failure but it did not have any and it is working!
what should I say to the people who are not familiar with the Markl's efforts?

Unless there is a base support(s) under the control valve set that in fact transform the upper support in something useless.

This or "steel is steel" and we really spend money for nothing.

Nice support anyway.

Regards,

Actually, there is no support beneath the control set!
