You guys got me thinking about these solenoid's but for a different
purpose. I fabricated a cable/pulley system for opening and closing my VBT
flood valve as it is under the floor boards and not in a convenient
location on a K-350. Do you Solenoid guys happen to know about how much
pressure a plunger can exert? That might be a great way to rotate the valve
90 degrees easily.
