Product Overview
The Eaton CVU 16 EFP1 B29 19 31 EN 116 is a high-performance proportional cartridge valve from the Vickers by Eaton line, engineered for precise electro-hydraulic flow and pressure control in demanding industrial circuits. Operating on a two-stage proportional control principle, this valve modulates spool position proportionally to an electrical command signal, enabling infinitely variable flow metering rather than simple on/off switching. The CVU series cartridge design allows direct insertion into a machined manifold cavity, minimizing leakage paths, reducing system weight, and simplifying hydraulic circuit integration. With a nominal size of NG16 (CETOP 16 / ISO 16), this valve is suited for medium-to-high flow applications where accurate velocity control, smooth acceleration and deceleration ramps, and repeatable pressure regulation are critical to overall machine performance and energy efficiency.

Engineering Features & Advantages
- Precision Proportional Metering: The EFP1 control variant delivers highly linear flow-to-command characteristics, allowing accurate velocity profiling and smooth ramping of actuators without the shock loads associated with directional valve switching.
- Integrated Position Feedback: Closed-loop spool position sensing ensures repeatable performance, minimal hysteresis, and consistent response regardless of temperature or pressure fluctuations.
- Cartridge Construction: The slip-in cartridge design reduces external leakage points, simplifies manifold machining, and enables compact, high-density hydraulic power unit layouts.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve components rated for millions of cycles in high-duty hydraulic systems.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Vickers / Eaton OEM standards, ensuring drop-in interchangeability without manifold modification.
Typical Industrial Applications
This proportional cartridge valve is widely deployed in plastic injection molding machines for precise injection and clamping speed control, metallurgical presses requiring accurate force and position regulation, CNC machine tools and machining centers for smooth axis feed and tool actuation, and general heavy industrial hydraul
