Does any company make a 1" threaded double-wafer check valve?
Does any company make a 1" threaded double-wafer check valve?
(OP)
I need a 1" or .75" double-door/double-disk check valve like this one: 
With or without the spring is fine; the problem is, I can't find it in 1". It seems they only make these for larger piping systems (2"-48") and in the wafer style or one of the ones where its bolted by the flange.
It needs to seat on metal... Not like these which get jammed up with enough pressure. http://www.flexi-hinge.com/index.php?option=com_co...
Any help with this would be greatly appreciated.

As implied above, there is no need in industry for such a small specialized valve. Rather: There is not enough need anywhere else in the world for enough such valves to make it worthwhile for anybody to try to build, stock, ship, and sell them.
Why do you think you need this particular style check valve in such a small size?
Why threaded/
Why a wafer valve at all?
I'm not arguing that you have decided you "want" such a valve, I'm simply asking why you think you need such a valve.

Am i reading it right? must be not enough pressure. Go try with high pressure and check whether it will jam or not.

All I want to know is if something like this exists.
The humor really misses its mark.

I hope is for low service.
