An electro-hydraulic control module for deactivating and reactivating intake and exhaust valves in an internal combustion engine comprising a series of stacked plates that form hydraulic valves, manifolding for supply, control and exhaust hydraulic flow and supports electromagnetic solenoids for activating the hydraulic valves. The plate structure is economical to manufacture and is advantageously small in vertical size. A bleed circuit keeps the hydraulic system relatively free of air to achieve fast, reliable and repeatable performance.
