Butterfly valve with a globe valve type of body
Butterfly valve with a globe valve type of body
(OP)
Hello, Experts,
I want to determine the valve body min thickness for butterfly valve with globe valve type of body.
The min thickness of the butterfly valve body should follow ASME 16.34 or API600?
My understanding is :
Face to face: API 600 since the customer asked me to develop butterfly valve with a Face-to-face dimension per API600.
Min thickness: ASME 16.34.
Is this correct?
Thanks

Corrosion resistant, exotic alloy valves from The Alloy Valve Stockist in Barcelona, Spain http://www.gate-valves.com

the flow regulation part uses butterfly valve disc, while the valve shell uses globe valve's face to face dimension

What size and what rating?
prognosis: Lead or Lag

Is this actually necessary?
Using an existing valve/normal length plus a separate mounting/extension piece would in most cases be far cheaper and faster.
BFL as regulation member indicates not very high pressures, and extension pieces can be made to exact lengths without high cost. You shold be able to find local producers all over the world. Example: http://www.marlener-metall.com/en/Products/index.h...
Additional info: Some BFL valves for some fluids and pressures and dimensions are already available on the market with building length longer than the normal wafer/short pattern. For instance could some double eccentric BFL valves replace (soft-sealing) gatevalve lengths directly.

I agree with all of your ideas. Use API 600 Face to Face dimension to develop the valve.
