HYDRAULIC CONTROL VALVE (FLOAT OPTION) YM4300 Custom made aluminum compression testerHYDRAULIC CONTROL VALVE (FLOAT OPTION) This valve has a more expensive "float"option. Float allows you to pull the lever to raise (for example), and push to lower but also adds a 'third' position just beyond the lower where the pressure is just released completely. This is great for a box blade to skim the ground or dump trailer where you just want the cylinder to lower naturally and not try to force it down.
