Achieve dynamic, high-capacity pressure regulation with the HD DRE/DREM Series. Available through Thm Hydraulics, these proportional pressure reducing valves allow you to infinitely adjust the working pressure of a secondary hydraulic circuit in direct relation to an electrical command signal. Whether you require standard proportional reduction (DRE) or the added security of a manual maximum pressure adjustment (DREM), this series is built for high-performance industrial environments. Capable of managing operating pressures up to 315 bar and high-volume flow rates up to 300 L/min, the DRE/DREM series is the ultimate solution for protecting sensitive downstream actuators while maintaining automated control.

Core Technical Specifications:-

• Component Architecture: Pilot Operated Proportional Pressure Reducing Valve
• Model Type: HD-DRE (Standard) / HD-DREM (With Manual Max Pressure Protection)
• Maximum Operating Pressure: Up to 315 bar
• Maximum Flow Capacity: Up to 300 L/min
• Repeatability Precision: < ±2%
• Recommended Electronic Control: VT-2000S 40 (Amplifier)
• Mounting Styles: Sub-plate mounting and Manifold mounting

Key Features & Engineering Advantages:-

• Infinitely Variable Reduction: Unlike fixed mechanical reducing valves, the DRE series allows your PLC or control system to change the downstream pressure on-the-fly. This is critical for machines that cycle through different force requirements or handle various material densities.
• DREM Integrated Safety: The DREM model features a manual "maximum pressure" adjustment screw. This acts as a secondary mechanical failsafe, ensuring that even in the event of an electronic signal failure, the downstream pressure can never exceed a safe, manually set limit.
• High-Precision Repeatability: With a precision rating of less than ±2%, the valve ensures identical hydraulic performance across thousands of cycles, eliminating pressure drift and ensuring part consistency.
• Optimized Dynamic Response: Features calibrated delay components (1.5 ms with buffeting / 4.5 ms without buffeting) to ensure smooth pressure transitions, preventing the hydraulic "chatter" and shock that can damage sensitive sensors and cylinders.
• Unified Control Solutions: For seamless commissioning and optimal accuracy, both the proportional valve and the matched electronic amplifier (VT-2000S) are sourced from a single supplier, ensuring perfect factory-calibrated signal mapping.
• High Flow Management: Engineered to stabilize and reduce pressure at flow rates up to 300 liters per minute, making it suitable for larger industrial actuators and complex manifold systems.

Ideal Industry Applications:-

The programmable pressure regulation and 300 L/min capacity make the HD DRE/DREM Series the premier choice for:

• Precision Machine Tooling: Governing the exact clamping and holding pressures for automated CNC fixtures where material thickness or tool-load varies.
• Injection Molding & Plastics: Precisely controlling auxiliary circuit pressures for core-pulls and ejectors to prevent part deformation.
• Secondary Circuit Stabilization: Protecting low-pressure components in a high-pressure system, such as steering circuits or brake systems on heavy mobile equipment.
• Hydraulic Test Benches: Enabling engineers to automate complex pressure-drop and durability test profiles via digital control.

Why Choose the HD DRE/DREM Series?

• Digital Command Over Fluid Power: Stop making manual adjustments for every new job. This valve puts the secondary pressure controls directly into your software for instant "recipe" changes.
• Protect Your Sensitive Assets: The DREM model provides the ultimate "belt and braces" safety—electronic flexibility combined with a hard mechanical pressure limit to prevent component blowout.
• Eliminate System Shock: The advanced damping and buffeting control ensure that even during rapid pressure shifts, your hydraulic lines remain quiet, stable, and vibration-free.
