Using 3pc Ball Valve to Transition from Pipe to Sanitary Tubing

[bigpolymerguy]

Currently designing a line from an existing reactor with a 150# 3" Raised Face Flange on the bottom. This line will be stainless sanitary tubing for easy connection/disconnection and cleanability. I am thinking about using a 3-piece Ball Valve with a 150# Flange end-connection on the top and 3" Tri-Clamp stainless tubing end-connection on the bottom to transition pipe specs while minimizing stack-up.

Does anyone here have experience with an install like this? I am looking at the FloTite MC350 for this application.

Thanks.

Edit: spelt out some abbreviations to alleviate any confusion and refined my question.

So is "3"TC" 3" transparent polycarbonate tube?

Can't see this being a thing anyone makes. You will need somehow to transition to a class 150 flange.

More likely to find a polycarbonate flange end or more likely a stub end and then use a metal backing ring to bolt to the valve.
That's the way I would do it for PE pipe anyway.

But note 3" class 150 isn't 3" OD, it's 3.5". Don't know what dimensions they make that sort of pipe to?

Thanks for the response, LittleInch.

The TC is actually referencing a Tri-Clamp end-connection. Basically transitioning from Sch40S 316SS pipe to 316SS polished sanitary tubing, and instead of making that transition via a reducer/adapter, transitioning via the valve itself. FloTite's multichoice (MC350) valve looks like it could work, but I was wondering if anyone here has experience with a configuration like this.

I would just order a valve with flange one end and weld end the other then just weld your tri clamp connector onto the end. Would be the same dimension if the valve supplier did it.

Not sure about dimensions, but you might need to stick in a 3 5 to 3 inch reducer somewhere.
