High-Flow Proportional Cartidge Valves


Our direct acting high-flow proportional valves have 5 to 10 times the flow compared to conventional valves with similarly sized coils.  We use Step-Bore Technology and years of experience to attain this size and power advantage.

With this power advantage, we can replace sluggish two-stage valves with responsive high-flow direct-acting valves.  Advanced internal dampening, as well as proprietary machining processes developed by Prince Industries, ensure a highly-responsive and stable electro-hydraulic system, with low hysteresis and precision control.

Applications include pump controls, transmission control and various pressure control systems.

Contact QP Hydraulic engineers to discuss how we can improve the efficiency and response of the hydraulic system on your OEM mobile equipment.
