Bill,
is the vibration randomly in any direction or mainly in one particular
direction? I had the same problem once and then I just oriented the
valve (respectively the plunger's orientation) perpendicular to the
vibration direction. That worked well, but might not suitable for you,
but I could imagine that your solid organ pipe is just axial.
As others suggested, a small ball valve would do the job as well:

Testing shows that the Lake Axial Solenoid valve in my pneumatic
payload separation system is leaking at 125 psia despite a 1000 psia
rating (two valves tested, both leaked); the leak is through the valve
and caused the latchup of the payload to the vehicle to fail within an
average of four minutes. Additional testing on my vibe table showed
latch failure in less than one minute in ten tests.
Can anyone suggest a solenoid valve good for at least 250 psia and
unlikely to leak under vibration?
Alternative suggestions to using a solenoid valve are welcome.
Thanks,
Bill
