I bet you could wrap bike handle bars with that tape!

[DrZarkloff]

@JefferyHunt You probably could. I don't know how long it would last.

Your remark is offensive and vile. You have been reported and blocked from replying to me.

Also I try to stay away from Sporlan and Parker valves, I think they are junk, and I much prefer and trust Alco valves. In all my refrigeration experiences I have came across only 3 bad Alco valves as opposed to 15 bad Sporlan, and 5 bad Parker valves. Alco makes their power heads out of stainless steal. Sporlan does not, and I have seen several heads rust open and loose their charge, thus closing the valve, and causing system restriction.

Great info here. However I myself would of just replaced the expansion valve as a whole. This looks to be an external equalizing expansion valve, as it has 3 ports, I am suprised to see that it's actually brazed into the lines, most valves in the commercial refrigeration equipment are flare nutted, which in time they loosen and leak freon, I can't begin to tell you how many leaks I have found in these, most of the time it's noted by oil being present in the condensation water.

Not a bad description but a few little hints. The power element can be hard to start on the thread because of the pins.By leaving the superheat assembly screwed in on one or two turns only there is less tension against the element diaphragm by the pins. It also prevents scoring of the diaphragm by the pins. I would not recommend trying to put the element on first and then the superheat adjustment assembly as then you have to try and compress the internal spring ,again messy if slips occur.

Hey Dr. Z., thank's again for an awesome experience through your camera lens! Wish I was there to help you out and learn from you. Hey by any chance would care in maybe making a video or videos on E. P. R. Valves, H. P. R. Valves and C. P. R. Valves?

I cannot believe there is actual "apprentices" or "tradesmen" asking on a bloody youtube video to help out their own real world problems. It's ridiculous. If you can't figure it out yourself you should be fired, or you're in the wrong trade. Actually get out of the trades altogether. Go to university and waste your time for 5 years.

should have put a trolling disclaimer. oops.
