RT on/off problem

[Small Block]

I've got : X-Valves, ULE bodies, RPG Splinter rails, Logic UMF frames, and using a HP Corssfire tank.

Now I have the same issue with two valves and two different RT on/offs.

The on/off pin gets stuck in the valve. I've oiled the pins and on/off assemblies with no luck. It'll shoot but I can count 2-3 seconds before I hear the click of the pin/sear resetting. If I try to shoot before that it just chuffs. The on/off o-ring (#22) seems alittle tight on the pin.

When I go to remove the on/off assembly the pin and o-ring stay in the valve and the rest of the on/off comes out. Then I need to grab the pin and pull it out with needle nose. The on/off o-ring (#22) seems alittle tight on the pin.

That's the better of the two, the other on/off pin gets real stuck and I have to de-gas the gun and pull it apart.

Now I thought I could've had the triggers adjusted to the point where they were pushing the pins up too far. I backed out the screws so they were flush with the back side of the trigger and the same thing happens.

No problems with the ULT installed, I'm thinking about picking up a second one now. In fact I've only ever used the ULT so this RT on/off is looking like a bad idea to me now.

So any suggestions or tips? Should I try a shorter pin? Or maybe a new #22 o-ring?

Thanks for any help!

That could actually exacerbate the situation as it could push the pin up even farther. You want a .5mm/ 1/16" gap between the back of the trigger and the sear pin.

Are you using an HP tank? The RT family of valves use the tanks output pressure to force the on/off pin back down. An LP tank could cause the problems you are describing.

If not, it is most likely a bolt problem, or your screws are too tight.

My on/off pin sticks in my X-valve too and it works fine.

Yup I'm using a HP tank. Even using an Adj. tank at 1000 psi output it does the same thing.

The body screw is snug and the field strip screw is finger tight.

By backing the trigger screw "out" I'm actually increasing the gap/space between the trigger and sear rod. I thought originally that I had the gap too close and was pushing the pin up too far. That's why I backed it out.

I'll try backing it out again and making sure I can insert a 1/16" allen key in the gap. Maybe I still had it too close.

I just thought it was wierd that it worked ok with the ULT but not with the RT.

Thanks!

**Edit**
I backed out the trigger some more and still had the same problem. BigEvil suggested I loosen the field strip screw and see if it helps. That did the job! Now it's hand tight with the marker aired up. Before it was hand tight before air.
