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
