You remeber correctly, at 24V a burkert cant lift the plunjer to fire the valve at pressures above 850 psi-depends from solenoid to solenoid, but the pressure wont vary much- because a burkert was meant to fire 750 psi max. Overvolting the coil to 36V makes it possible to fire the valves at for us normal pressures. Also, the tests that Mike and company did on burkerts show that the body can take way more than 1000 psi.

Mike encountred this problem in Las Vegas, nice and hot day, So the pressure inside the bottle was maxing out.

After this, and seeing an increase in burkert use in feathers, were 24V is rare, Bugs made a voltage step up, and that does about anything between 9.6V and 24V to 36V.Amperes are limited tough.Also, the system is safe but cheap.
