Product Overview
The DANFOSS 1DR30-P-40-S is a direct-operated pressure reducing cartridge valve engineered to maintain a constant reduced outlet pressure regardless of fluctuations in inlet pressure or downstream flow demand. Part of the Danfoss 1DR series of screw-in cartridge valves, this unit features a balanced spool design that senses downstream pressure and modulates the spool position to throttle inlet flow, delivering stable secondary pressure to sensitive hydraulic circuits. With a compact cartridge footprint and industry-standard cavity, the 1DR30-P-40-S integrates directly into manifold blocks and custom hydraulic integrated circuits (HICs), making it ideal for space-constrained industrial systems requiring precise pressure control without the bulk of line-mounted valve bodies.

Engineering Features & Advantages
- Precision Pressure Regulation: The direct-acting spool design delivers accurate, repeatable reduced outlet pressure, protecting downstream actuators, proportional valves, and instrumentation from over-pressure events.
- Balanced Spool Construction: Minimizes the influence of inlet pressure variations on the regulated outlet, ensuring stable secondary pressure across the full operating flow range.
- Compact Cartridge Format: Screw-in design reduces manifold size and eliminates external leakage paths associated with line-mounted pressure reducing valves.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve for long service life and low hysteresis.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Danfoss 1DR30 cavity and OEM standards, allowing drop-in servicing without manifold modification.
Typical Industrial Applications
The DANFOSS 1DR30-P-40-S is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and construction & marine hydraulic systems where a stable, reduced pressure supply is required for pilot circuits, clamping functions, and secondary actuator control. Its cartridge configuration is particularly suited to manifold-based hydraulic power units and custom integrated circuits demanding high-density valve packaging.
