HD – 3DREP6 – Proportional Pressure Reducing Valve of 3-Way Design
Achieve high-fidelity pressure regulation in your pilot or auxiliary circuits with the HD 3DREP6 Series. Available through Thm Hydraulics, this 3-way proportional pressure reducing valve is directly actuated by wet-pin DC proportional solenoids. Designed for precision rather than raw bulk, it is the ideal solution for limiting system pressure in direct relation to an electrical command value. With a maximum operating pressure of 100 bar and a controlled flow rate of 15 L/min, the 3DREP6 offers the rapid response and extreme repeatability required for the most sensitive industrial automation and pilot control stages.

Key Features & Engineering Advantages:-
- Ultra-Precise Repeatability: With a precision rating of less than 1%, this valve ensures that your hydraulic system performs with identical accuracy across thousands of cycles, eliminating pressure drift.
- Rapid Dynamic Response: A delay component of less than 3 ms allows for near-instantaneous pressure adjustments, making it perfect for high-speed control loops and sensitive pilot stages.
- 3-Way Design Versatility: The 3-way configuration allows the valve to reduce pressure from the primary line and vent excess pressure to the tank, providing a stable, "dead-beat" pressure control even during actuator movement.
- Wet-Pin Solenoid Technology: The proportional solenoids operate within the hydraulic fluid (wet-pin), which provides natural lubrication and cooling to the armature, significantly extending the valve’s service life in high-cycle environments.
- Unified System Source: Both the high-performance valve and the electronic amplifiers are sourced from a single supplier, ensuring perfect signal-to-pressure calibration and reducing troubleshooting time during commissioning.
Ideal Industry Applications:-
The high precision and 100 bar threshold make the HD 3DREP6 Valve the premier choice for:
- Pilot Control of Large Valves: Serving as the high-accuracy "brain" that provides pilot pressure to shift large, high-flow proportional directional valves.
- Clamping Force Modulation: Precisely adjusting the clamping pressure on CNC machines to hold delicate parts without deformation.
- Brake & Tension Control: Governing the exact hydraulic pressure for industrial braking systems or web-tension rollers in paper and textile mills.
- Hydraulic Test Benches: Providing stable, electrically-variable pressures for calibrating sensors and testing small hydraulic components.
Why Choose the HD 3DREP6 Series?
- Master the Nuance: When your application requires a soft touch and absolute repeatability, the 3DREP6 delivers a level of control that standard mechanical valves cannot match.
- Soft-Start Capability: By utilizing the VT-3000 or VT-3006 amplifiers, you can program custom pressure "ramps," preventing the hydraulic water-hammer effect and protecting your system’s seals and fittings.
- Compact & Clean: Designed for standard sub-plate mounting, it integrates perfectly into existing manifold stacks, keeping your hydraulic layout organized and professional.
