    Spring Adjustment in Pressure relief valve

    Hello all, I read that in pressure relief valves(hydraulics), there is knob, which can be adjusted to increase the spring tension, which in turn increases the relief pressure(pressure which pushes the spring and opens a path to tank). This spring tension depends upon the spring constant, which...
