Abstract
A fluid flow control valve which has a pair of solenoids that move a hollow ball valve between a first position and a second position. When the ball valve is in the first position, fluid is allowed to flow from an inlet port to a cylinder port. When the ball valve is in the second position, fluid is allowed to flow from the cylinder port to a drain port. The ball valve sits against one of two valve seats which are constructed from steel and a have radial shape that conforms to the shape of the ball. The hystersis of the steel maintains the ball valve in one of the two positions, so that power does not have to be continuously provided to the solenoids. The ball valve has a hollow inner chamber which significantly reduces the weight of the ball and increases the response rate of the control valve.
