Bi-directional Stainless Steel Ball or angle valve for Transfrmr Oil Tank drain

1.The major worry is damage to the valve and corrosion from the hot transformer oil.

2. Be sure the grade of stainless and valve packing is compatable with hot transformer oil. If the transformer has dioxin in its oil that is another worry in relation to the quality of the valve.

3. Are the valves in question protected by a shield of some sort to protect them from damage? Also it would be prudent to put a second valve in line with the first one for safetys sake and be sure to buy valves that can be locked with a pair of locks of some kind if you plumb in two valves in series as it is an added level of safety.

Dear friend,

what you are telling have a point.But my major worry is that from where i should find a vendor who supply these "three-in-one" valve for tranformer oil work and of required specification.

Thanks and regards

Click on the GlobalSpec logo at the top right hand corner of this page and do a search on "ball valve". It will give you the names of over 900 manufacturers, if you refine the search on the next page to stainless steel ball valves you will have over a thousand products to choose from. One of them is bound to suit you application.

Dear friend,

that is another big problem, i.e. to choose one valve from the thousand products.

What we wanted was the vendor to specify a valve which satisfy all our specified requirements. That is some thing standard normally used for Transformer Oil drain services.

But on browsing what I get is:

SS Ball valve full port or standard port - I dont know which one is better to choose.

Valve body of one piece or Two piece or Three piece - I dont know which one will be better to choose and why (It would have been easier for me if that would have been a ladies swim suit)

They have various various valve seats to choose from - metal, PTFE etc. - Now it becomes difficult to choose

Although the ball valve is specified as Stainless Steel but the parts are defined as ASTM 351 etc. etc. - Now to select amongst these becomes a problem.

I will be thankfull of all the gurus for any further guidance..............

Thanks and regards.

Once you get the list of companies that manufacture stainless ball valves if you click on the companies name it will take you to a page that has an email link to that company. I would use this to send an email detailing your problems the 4 or 5 companies that produce the greatest variety of stainless valves. I would also send an email to the companies that manufacture custom valves. I am sure one of them will be able to help you.

Dear Sir,

Thanks a lot, I will do that. I hope that will help me.

Thanks and regards.
