Here's what I found for a 24" ball valve price online:
Size 24 inch (DN600) Pressure Rating Class: 150-1500 (PN20-260) Operation: Gear Operated Unit Price: $6900-$32000
A couple things to note. These valves are manually operated. Inconel is much more expensive than 316 stainless steel. Inconel is much more difficult to machine than stainless steel. These differences would likely add significantly to the final price.
Found one reference which states that Inconel machined pieces would cost about 5 times more than 316 SS machined pieces.
On average, inconel pieces cost up to five times more than its stainless steel counterparts because it is a much rarer material and requires more work to produce as a result.
Remember that "post" on "X" from Aug. 16? It started with the words "Material in." Those metal pieces on the pallets were likely the Inconel material that MVNT is now machining into balls for their ball valves.
Believe me, if any other parts of these valves are made from Inconel, a 24" valve would run at least $100K! I mean this is super exciting if they are expecting to sell around 200 valves made with Inconel parts. Not only would those valves be super expensive, they would also likely take a lot of time to machine. I would expect MVNT would have to have at least 3 of those CNC machines each running 8hr/day to complete the production of 200 valves within a year. That's a massive, massive project for a small valve company.
Anyway, hopefully we'll learn more as MVNT continues to post on "X" weekly as they have been doing these past 3 months.
By the way here's the link to the post showing the "material" for machining being stored in their facility.
Material in. Commencing machining for a valuable client. This is a production run of proprietary parts. $MVNTpic.twitter.com/xaUxTrkyti
