was wondering if your valve is like mine and sticks first few shots if the valve sets for any small amount of time , minutes , takes several shots to get the valve opening with out sticking and making weak first few shots , starts out several hundred ft low and climes with each shot , , takes 3-4 shots to get it shooting back up , just wondering if others had this problem , when i first ordered it they kept sending it leaking , and i would send it back right away and they would forget to fix it then some one would send it back and same thing , but finally it came back after over lots of months and it wasn't leaking ! but its sticks , even just sitting in my drawer i cant just walk up and push the valve open with my thumb until i break it free with something hard to push against , and push hard ! hoping Motor head has a thought ! or any one who knows
any one have a JSAR Marauder/Armada SS Balanced Valve, .177, .22, .25 ?

I don't have that particular valve, but do have a potential fix for you to try that worked for me. On a sticking valve I polished the stem and sealing surfaces to a mirror finish. Then I use Krytox 205 grease on all of the valve's moving surfaces and o-rings, including metal on metal. I also changed out the standard black o-rings for extruded urethane o-rings in 90 duro. Get them from here.

These done for my personal guns using these type valves. I don't offer these mods for sale due to time and effort / cost in doing so.
Buy a COTHRIN power house if you can't do these mods yourself etc ...

Besides sticking I couldn't get mine to quit leaking modded it into a simple balance valve that Bob Stern came up with worked alot better
