Command absolute, electronically monitored fluid routing in your most massive hydraulic circuits with the THM 4WRKE Series Pilot Operated Proportional Directional Valve. Engineered for extreme-scale fluid power systems, this advanced valve features state-of-the-art electrical position feedback and a built-in amplifier (OBE - On-Board Electronics) directly integrated into the unit. Capable of smoothly processing staggering flow rates from 25 up to 600 L/min while sustaining relentless 350-bar operating pressures, the Component Series 3X delivers uncompromising, automated precision for complex heavy-duty applications. Spanning sizes 10 through 32, the 4WRKE Series provides the highly accurate flow and directional control required to automate the massive cylinders driving modern civil, road, and earthmoving machinery.

Core Technical Specifications:-

• Valve Architecture: Pilot Operated Proportional Directional Valve
• Model Series: THM 4WRKE (Component Series 3X)
• Standard Sizes: Size 10 to 32 (NG10 to NG32)
• Maximum Operating Pressure: Up to 350 bar
• Rated Flow Rate: 25 to 600 L/min
• Control Technology: Electrical Position Feedback on Main Spool with Integrated Amplifier (OBE)

Key Features & Engineering Advantages:-

• Integrated Control Electronics (OBE): Features a highly advanced built-in amplifier. This "On-Board Electronics" design drastically simplifies machine wiring, entirely eliminating the need for bulky external amplifier cards in your electrical cabinets and ensuring perfect, factory-calibrated plug-and-play synchronization.
• Main Spool Position Feedback: Utilizing closed-loop electrical position feedback on the main spool, the valve constantly monitors its exact physical state. This guarantees that your massive hydraulic actuators receive highly accurate, repeatable flow rates entirely independent of fluid viscosity or violent load fluctuations.
• Pilot Operated Power: Actuation is driven via a highly responsive proportional solenoid pilot stage. This allows a low-power electrical signal to effortlessly shift the massive main spool, seamlessly routing up to 600 liters of fluid per minute without mechanical cycle lag.
• Fail-Safe Centering: Engineered with a robust spring-centered main spool. In the event of an electrical power loss or control signal failure, the spool automatically returns to its neutral, safe position, instantly arresting cylinder movement to protect the job site.
• Standardized ISO Integration: Designed for bottom plate installation with an interface face that strictly conforms to standard ISO 4401 (Sizes 10 to 32), guaranteeing seamless drop-in integration into your massive custom manifold blocks.
• Serviceable Solenoid Stage: Equipped with a threaded-type replaceable solenoid coil, allowing field technicians to perform rapid electrical maintenance without ever breaking the main hydraulic seal, maximizing critical machine uptime.

Ideal Industry Applications:-

The breathtaking 600 L/min capacity, plug-and-play OBE, and closed-loop electronic precision of the 4WRKE Series make it a mandatory automated control component for:

• Heavy Civil & Road Construction Machinery: Providing the ultra-precise, variable-speed directional control required for the massive lifting cylinders, heavy leveling screeds, and automated steering systems on large-scale asphalt pavers, concrete slipform pavers, and deep-cut road milling machines.
• Extreme Earthmoving Equipment: Delivering exact, repeatable fluid routing to the primary boom, stick, and massive bucket circuits on 50+ ton mining excavators and colossal wheel loaders operating under intense continuous loads.
• Large-Scale Industrial Manufacturing: Managing the exact clamping forces, rapid advance, and highly metered pressing speeds of heavy multi-stage metal-forming presses and deep-drawing equipment.
• Heavy-Duty Material Handling: Ensuring flawlessly smooth, perfectly metered lifting and stabilization maneuvers on high-tonnage industrial cranes and heavy marine winches.
