Running 2 valves, each for 2030 minutes, I would drain full 2000mAh battery no problem. I had to look for another solution something that would not require constant power to stay open. I found servovalves where a servo drive is able to open and close a ball valve. Great idea, low power consumption (5V, 50mA, 5 seconds to fully open or close).
They are available at Parker Hydraulic Technology Centers (HTCs) or through Parker's Industrial Systems Business Unit.

In dynamic structure test, the specimen of hydraulic servo shaking table contains not only inertia load but also elastic load. The specimen herein is simplified as a springmassdamping system, and the mathematical model of the hydraulic servo shaking table is established by theoretical analysis. The coupling between specimen#x2019;s elastic load and shaking table itself produces resonance ...
To analyze the deflectorjet servo valve's internal flow characteristics, a theoretical model of the complied flow distribution in the deflector plate is established based on the offset jet attachment theory. When the deflector plate offsets, jet attachment parameters are attained to figure out the jet's bending and colliding process. On this basis, an analytical method of acquiring the ...
