I haven't had much luck at all! But I have decided to go ahead and use the valves. Apparently Exxon has these valves in service and the they are manufactured to the specifications needed for my application. Delivery time was the reason I was considering using them so I was on a short time frame for a decision. I will let everyone know if I have any problems with them!
I have used a limited amount of them and have not had any problems. They are just another OEM branding valves shipped from different locations in China. I have met with one of the partners and he is an honest stand up guy. I would say for standard material valves they should not be any different from any other 20 standard manufacturers.
