Product Overview
The Danfoss PFR2-10-S-0-/0.70 is a precision two-way proportional flow control valve engineered for accurate, infinitely variable regulation of hydraulic flow in industrial and mobile hydraulic systems. Operating on a proven spool-and-sleeve metering principle, the valve modulates flow proportionally to the electrical input signal supplied to its proportional solenoid, enabling smooth, stepless control of actuator speed and motion. With a nominal flow rating of 0.70 L/min, this model is specifically calibrated for low-flow, high-precision metering duties where fine resolution and repeatable response are essential. As part of the Danfoss PFR2 series, it serves as a critical control element in load-sensing and pressure-compensated circuits, delivering stable performance across demanding duty cycles.

Engineering Features & Advantages
- Precision Flow Metering: The spool-and-sleeve metering geometry, paired with a proportional solenoid, delivers highly linear flow output relative to the command signal, ensuring accurate and repeatable actuator speed control even at the low 0.70 L/min flow range.
- Fast Dynamic Response: Optimized solenoid force characteristics and low-friction spool design provide rapid response to signal changes, minimizing hysteresis and enabling precise closed-loop control in servo-proportional circuits.
- Stable Low-Flow Performance: Specifically calibrated for fine metering duties, the PFR2-10-S-0-/0.70 maintains smooth, chatter-free operation at minimal flow rates where standard valves lose resolution.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve components resisting contamination and wear for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Danfoss OEM standards, ensuring drop-in interchangeability without circuit modification.
Typical Industrial Applications
The Danfoss PFR2-10-S-0-/0.70 is deployed in applications demanding precise low-flow control, including plastic injection molding machines for accurate injection and holding pressure modulation, metallurgical presses requiring fine ram speed regulation, CNC machine tools and precision test stands where smooth actuator motion is critical, and mobile hydraulic systems with load-sensing circuits needing proportional flow management. Its low nominal flow rating makes it particularly suited to pilot circuits, small-bore actuator control, and any hydraulic function
