Achieve absolute, electronically variable pressure regulation in your precision circuits with the THM EDG Series Proportional Pressure Relief Valve. Engineered specifically as a highly responsive pilot stage, this compact unit masterfully combines a specialized small DC solenoid with a direct-acting relief mechanism. By strictly controlling hydraulic pressure in direct proportion to the electrical input current, it ensures perfectly metered, shock-free force scaling. Capable of processing a dedicated pilot flow of 2 L/min and sustaining maximum operating pressures up to 245 bar, the EDG Series is incredibly versatile. It functions flawlessly either as the primary relief valve in highly sensitive low-flow hydraulic systems or as the critical pilot control stage for larger proportional electro-hydraulic valves managing flows between 60 and 120 L/min.

Core Technical Specifications:-

• Valve Architecture: Pilot-Operated Proportional Pressure Relief Valve
• Model Series: THM EDG
• Maximum Operating Pressure: Up to 245 bar
• Direct Pilot Flow Rate: Up to 2 L/min
• System Flow Adjustment Range: 60 ~ 120 L/min (When acting as pilot for main-stage control)
• Actuation Technology: Small DC Proportional Solenoid
• Electronic Requirement: Must be operated in conjunction with an applicable power amplifier

Key Features & Engineering Advantages:-

• Direct-Acting Precision: The integration of a small, highly responsive DC solenoid directly actuates the relief mechanism. This guarantees that system pressure rises and falls smoothly in exact proportion to your input current, entirely eliminating the aggressive pressure spikes of traditional manual valves.
• Dual-Purpose Versatility: Highly adaptable to your manifold design. It can act as the standalone pressure relief valve for specialized, low-flow (2 L/min) sub-circuits, or serve as the intelligent pilot "brain" driving massive main-stage valves controlling 60 to 120 liters per minute.
• Amplifier-Driven Accuracy: Designed to be paired with a dedicated power amplifier, ensuring the valve receives a perfectly conditioned, stable electrical signal for highly repeatable, hysteresis-free pressure tuning.
• Compact Manifold Footprint: The streamlined combination of the small DC solenoid and direct-acting body ensures the EDG Series consumes minimal space in crowded hydraulic blocks, allowing for denser, lighter power units.

Ideal Industry Applications:-

The compact precision and proportional scaling of the EDG Series make it an essential automated control component for:

• Heavy Civil & Road Machinery: Serving as the ultra-precise pilot control for the main-stage directional and pressure valves on large-scale asphalt pavers, automated motor graders, and heavy road milling machines.
• Advanced Earthmoving Equipment: Regulating the delicate, variable-pressure pilot circuits on modern, electronically controlled tracked excavators and high-capacity trenching equipment.
• Automated Industrial Manufacturing: Delivering exact, repeatable pressure signals to control the multi-stage clamping forces and rapid pressing speeds of advanced metal-forming presses and plastic injection molding lines.
• Precision Hydraulic Test Benches: Providing the highly stable, low-flow pressure regulation required for automated quality control rigs and advanced fluid power testing facilities.

Why Choose the THM EDG Series?

• Pinpoint Proportional Control: Translates electrical current into exact hydraulic force, ensuring your machinery executes programmed pressure profiles with zero deviation.
• System Scalability: Equally effective as a standalone low-flow relief valve or as the pilot stage for high-volume 120 L/min systems.
• Space-Saving Design: Delivers massive electronic control capabilities without expanding the physical size of your manifold block.
