Proportional Directional Valve Product Description

Core Performance Features

1. High-Precision Proportional ControlThese valves integrate advanced proportional solenoid technology, achieving linear synchronization between input electrical signals and output flow/pressure parameters. The 4WRPH6 series, designed with a 24L nominal flow rate, ensures stable and accurate control over the speed and position of hydraulic actuators, minimizing system response delay and enhancing overall operational stability. Whether for fine-tuning or heavy-load regulation, the valves maintain consistent control accuracy to meet diverse industrial requirements.
2. Superior Working Condition AdaptabilityConstructed with high-strength alloy valve bodies and wear-resistant internal components, the valves excel in high-pressure hydraulic environments typical of construction machinery, metallurgical equipment, and industrial automation lines. Equipped with the G24Z4 solenoid control module, they support a stable DC24V power supply and feature an anti-interference circuit design, ensuring uninterrupted operation even in complex electrical environments with strong electromagnetic interference.
3. Flexible Installation & Hassle-Free MaintenanceAll valve models adhere to industry-standard mounting dimensions, enabling direct drop-in replacement for compatible components in existing hydraulic systems without the need for structural modifications. The modular design of the solenoid assembly and valve core simplifies disassembly and maintenance procedures—technicians can quickly access and replace worn parts, significantly reducing equipment downtime and maintenance costs.
4. Broad Application CompatibilityThe comprehensive product range covers a full spectrum of flow and pressure specifications to match varied application needs. The 4WRPE, 4WRKE, and 4WRZE series are ideal for large-flow hydraulic systems, while the compact 4WRPH6 series is optimized for space-constrained equipment such as small construction machinery and agricultural implements. The specific model 0811404038 is engineered for scenarios demanding precise low-flow regulation, and the 4WRPH6C4B24L-20/G24Z4/M and 4WRPH6C4B24L-2X/G24Z4/M variants are well-suited for heavy-duty applications like hydraulic presses, injection molding machines, and mining equipment hydraulic systems.
