Refrigerant Flow Controls – Commercial

High style chrome name plate and logo, a new slick look for the expansion valve

Technical Significance:
The 893 compact thermostatic expansion valve, although short lived, was a significant marker of the times, as the industry, responding and at the same time shaping the market place, moved to ever more compact, more sophisticated engineering designs based on cumulative know how. A sign of the now rapidly changing times, Detroit would soon replace the 893 with the even more compact design, the 777.

Industrial Significance:
High style chrome name plate and logo, a new slick look for expansion valves in the early post W.W.II years, reflecting the new interest of manufacturers in the emerging field of industrial design

The now rapidly changing market place would trigger substantial investments in R and D by companies like Detroit. The life of this product would be a short one, soon to be replaced with an even more compact design, the 777. A sign of things to come.

By the middle of the 20th century, the pressure was on for a new generation of compact thermostatic expansion valves to meet the growing market for small commercial refrigeration appliances. The 893, designed for this market, would raise eyebrows, with high style nameplate in bright chrome with blue highlighting. A sign of the times, Detroit would soon replace it with the even more compact design, the 777, Model 893, Detroit Lubricator, circa 1952.
