FX Valve seat Panthera keeps turning

[danny5692]

I have got some problems with my Panthera. It usually shoots like a charm but every now and then the valve seat keeps turning of place.
Result is less power as the port is not in line anymore.
I have tried other valve seats but that doesn't solve the problem.

Does anybody else have this problem, and did you find any solution for it?

Yes my panthera did it and after replacing it, it's been holding fine.

It's indexed, so if it was installed correctly, it should not move out of place unless your shooting it below reg pressure, or have way too much hammer for the set reg pressure.

My drs did the same I spun it back straight and gave it a couple of love taps to make sure was seated and it has had air in it since I just don't let it get that low again

I found the problem. They upgraded the seat. So it was a known problem at FX.

1st production run?

Explains that.

Then your new valve should have the thicker shaft also.

I've replaced the valve two months after I got it.

So it's still the 1st version. I guess if your using lower power for the sub 12, it won't matter.
