4WEH25G Electro-Hydraulic Valve Product Introduction
The 4WEH25G electro-hydraulic directional control valve represents advanced hydraulic control technology, featuring a spool valve structure designed for industrial automation and mobile machinery applications. This valve achieves precise hydraulic circuit switching through electromagnetic actuation, demonstrating rapid response characteristics and consistent operational reliability. The valve body, constructed from high-strength alloy material, incorporates optimized flow channels to minimize pressure drop and enhance system efficiency.
Engineered for demanding working conditions, the valve maintains stable performance within a working pressure range of 21MPa to 31.5MPa, with oil temperature adaptability from -20℃ to +80℃. Advanced surface treatment processes enhance wear resistance of critical components, while precisely controlled mating clearances ensure long-term leakage control. Multiple electromagnetic coil options are available, including DC12V/24V and AC110V/220V configurations, ensuring compatibility with various electrical systems.
Functionally, the 4WEH25G features center position pressure relief capability and three-position/four-way control mode, enabling precise control of hydraulic actuators for start-stop, directional change, and pressure maintenance operations. Specially designed sealing elements and cushioning structures effectively reduce shifting impacts, making it particularly suitable for position-sensitive hydraulic systems. The maintenance-friendly design allows for in-line servicing, significantly reducing equipment downtime.
Typical applications encompass injection molding machine clamping systems, marine steering gear controls, mining equipment propulsion mechanisms, and metallurgical continuous casting installations. The modular design facilitates quick installation and system integration, with standardized interfaces compatible with mainstream hydraulic piping systems. Manufacturers provide professional technical support teams capable of delivering customized solutions based on specific operational requirements.
