Product Overview
The HAWE ED 31 K is a precision proportional pressure limiting valve engineered by HAWE Hydraulik for continuous, electro-proportional control of system pressure in industrial hydraulic circuits. Unlike a simple on/off relief valve, the ED 31 K modulates its pressure setting in direct proportion to an electrical command signal, allowing stepless, infinitely variable pressure regulation from a remote or automated control system. The valve operates on a balanced spool and seat principle in which an integrated proportional solenoid acts against a calibrated spring, shifting the pressure-limiting stage to establish the commanded set pressure. This design delivers fast, repeatable response and stable pressure holding, making the ED 31 K a core component in systems requiring programmable pressure profiles, soft-start ramps, and precise force or torque control. As a genuine HAWE proportional valve, it is built to the manufacturer’s exacting tolerances and is intended for direct integration into both new machine builds and OEM replacement applications.

Engineering Features & Advantages
- Precision Proportional Performance: The proportional solenoid and balanced pressure-limiting stage deliver smooth, stepless pressure modulation with high repeatability, enabling accurate force, torque, and load control across the full command range.
- Fast Dynamic Response: Optimized spool and seat geometry provides rapid reaction to command signal changes, supporting soft-start ramps, controlled deceleration, and programmable pressure profiles.
- Stable Pressure Holding: Low internal leakage and a robust pressure-limiting design maintain the commanded set pressure reliably, even under fluctuating flow and load conditions.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and contamination-tolerant clearances for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original HAWE standards, allowing straightforward retrofit into existing hydraulic systems without rework.
