Flow Control Valve - Power Steering

The Flow Control Valve - Power Steering from Detroit Speed Engineering is a precision hydraulic component engineered for builders and restorers performing cross-platform power steering system conversions. This adapter is essential when mating a GM-style pump to a Ford rack-and-pinion steering system—a common modification in hot rod, custom truck, and performance vehicle builds where OEM pump and rack combinations aren't available or compatible. The 2 gpm flow rating is calibrated for reliable pressure regulation across a broad range of steering inputs, ensuring predictable feedback and responsiveness without exceeding system pressure limits.

Constructed from steel with a zinc oxide finish, this valve housing resists corrosion and thermal cycling common in engine bay environments. The flow control mechanism inside regulates hydraulic flow volume to match the Ford rack's design specifications, preventing starvation during tight steering maneuvers or excessive pressure spikes that could compromise seals and hoses. Detroit Speed Engineering's design accounts for the pressure differential between GM pump delivery and Ford rack demand, making this far more effective than simple adapter fittings that ignore flow compensation entirely. The compact 1.8 x 1.05 x 3.95-inch form factor integrates cleanly into most engine compartments without requiring extensive plumbing rerouting.

This valve is indispensable for builders swapping early-generation GM power steering pumps into vehicles equipped with modern Ford integral-rack systems, or vice versa. Installation requires basic hydraulic line connections and minimal bracket fabrication; the valve threads or bolts into the pump discharge line upstream of the rack inlet. Proper hose sizing and fitting selection are critical—undersized lines will choke flow and overheat the pump, while oversized lines invite cavitation noise. For best results, flush the entire system after installation and verify pressure at idle and full steering lock using a calibrated gauge to confirm proper valve operation.
