1.Introduction of Ductile Iron Butterfly Valve


Ductile iron butterfly valve is used for isolating and regulating flow. The closing mechanism is a disc that allows for quick shut off, much like a ball valve. Butterfly valves are light in weight so they require less support. Unlike the ball valve, the disc is always present within the flow, therefore a pressure drop is always induced during flow, regardless of valve position. The disc is typically rotated a quarter turn when the valve is fully opened, but the valve may also be opened incrementally in order to throttle flow.

3.Q&A with a Ductile iron butterfly valve Distributor,Below is the transcript of the session;


Speaker 1: Ok so these are Ductile iron butterfly valve, we offer them in a ductile iron body, we will cover it in a wafer style, a lug style, as well as a wafer with alignment holes. Basically, these valves are ductile iron body, like I said wafer lug. Now we do offer it in a ductile iron nickel plated disc, with a Buna-N seat. We also offer it in a 316 stainless steel with a Viton seat, also with a EPDM seat, what other seats available?

Speaker 2: Teflon, essentially that's it. Teflon, EPDM, Buna-n, and Viton and the reason we offer different seats for these Ductile iron butterfly valvedepending on what the application these customers are running through. Here recently we've been having a lot of customers run through a lot of acid and acid will tear these valves up. So were working on something now to get an epoxy coated disc and to be able to withstand the effects of acid, and also you would want to use a Viton seat or a Teflon seat depending on what the percentage of acid.



Ductile Iron Butterfly Valve



Speaker 1: We do offer Ductile iron butterfly valve also- forgot to mention, sorry to cut you off. We do offer these in a two-inch all the way up to a twelve-inch. On the alignment holes right now what we do offer is only a four-inch, but we do have other sizes coming in a three, four, six and possibly an eight-inch coming soon.

Speaker 2: And we can get anything made to your specs. For example, we had some 48-inchDuctile iron butterfly valve, four pieces made for a company over in Russia. So we have the capabilities to ship international all over the United States and we can make anything built to spec.
Speaker 3: What is the pressure rating of these?
Speaker 2: 200 class, 200 pounds, or a 150 pounds.
Speaker 3: Water oil gas?
Speaker 2: Yes, well water along gas depending on the application. Now your ductile wafer ductile Buna, ductile iron disc, nickel coat plating, Buna-c is what you would want for water oil gas. When you get into gas pockets, crude oil stuff like that; that's got H2S in it.
