Thanks for your consideration.
Actually it s an Orion brand four inch class 900 Globe Valve.
It has a renewable seat ring that would be threaded because of its chuck nut and has welded because we could not open it.
So am looking for a instruction or procedure for that.
Thanks again everyone.
Would someone help me in the seal welding of renewable seat ring in the globe valves. actually looking for an standard instruction or process specification of seat ring seal welding in the globe valves.
