The Old Timer of Royal Oak, Mich., was a regular contributor to H&P years before we ever even heard of the internet. But most of his advice is just as useful — and interesting — today.
So rather than leave his wisdom printed on pages archived in our storage room, I pulled out issues from the late 1980s and early 1990s and have been reproducing relevant entries in this blog. Here is my 19th entry, which was originally published in the July 1989 issue:
Same valve, twice the flow
They calculated that they needed twice the flow to meet the time requirement. However, the existing valve was already flowing near its maximum capacity, and space didn’t allow for a bigger valve. Could we help? Quickly?
We dug out the catalog on the valve and were delighted to learn that it was a multipurpose design — it could accept pressure at any port. This meant it could perform like two 3-way valves in the same body.
They did as we suggested, and the valve performed as predicted, putting the nut runner back in business.
