When ever I install a hydraulic system in any of my models I put in an accumulator, just a piece of tube with 1 closed end a piston & rod coming out the other end and a spring I play with different springs until I have the on Off pressure range I need, 2 micro switches, last one turns off pump when rod is out, when rod retracts to first one the pump starts all controlled by a small reed switch, controling the start stop action of the motor. The pump only runs when not at high pressure once there it stops. I get instant response when valve opens. This gives me lots of battery life
