valve for chlorine water

[kiwi02]

We have the job to design a valve for chlorine water (for an offer), but we have no real experience in doing this. The customer would like to have alloy 59 or inconel 625. But the machining time and the material costs are very high. Maybe there is a cheaper solution or material according to the needs specified in the attachement. Thank you for help.

This might be better placed in a different forum such as one related to materials.

Ok. you are right, but we can´t find manufactory for this chlorine valve. Maybe you know somebody, who could do this. It is an inquiry of a very good customer of us and we want to help by finding a solution. Thank you for help.

Can't you use PVC?

We just manufactoring in steel, but maybe you know somebody who can do in plastic. There is another problem: the water is slurry and the temp is 250°C with 50bara (see attached file for more parameters).

I know one or two companies here that might be able to do it. But judging from your document, I think we are on opposites sides of the world.
You should be able to find someone closer, this is not too specialized of an application, I don't think

Dear unotec,

Can you post a URL to their company website where I can make contact?

Thank you

1. Try to repost at valve engineering forum to get a broader feedback.

2. Try for instance : Metso

(worldwide) Ballvalves or possibly butterflyvalves (BFL normally limited to pressure classes about 40 bar - but might exist for higher)

3. Stainless steel valve US

O-port valve.

Comment: None of the two suggested will give you cheap solutions, caused by the combination of fluid, temperature and size.

Before final design I would ask your customer/enduser, after I had done a brief market research, if he could adapt by going down in pressure design to PN40 or down in design temperature, or up in flow/down in size to get acess to a broader aspect of already commercially available produced and existing valve designs.

In addition and as mentioned by others: there is a broad availability of designers and producers of special valves, depending on where you are located.
