Product Description
4WRL & 4WRLE Series High-Performance Pilot Proportional Valves
Product Overview:
The 4WRL and 4WRLE series are pilot-operated proportional directional valves engineered for high-flow hydraulic systems. Spanning from Size 10 to Size 35, these valves are staples in metallurgical machinery, heavy-duty presses, and power plant control systems. The 4WRLE models feature Integrated Electronics (OBE), allowing for direct analog command input and closed-loop spool position control, delivering exceptional repeatability and dynamic performance.
Featured models include: 4WRLE16V120M-30/G24K0/A1M, 4WRLE16E-41/A1M, and compatibility for the full 4WRL10/16/25/35 range.
Key Technical Advantages:
Powerful Pilot-Operated Drive: The two-stage design utilizes a pilot stage to precisely actuate the main spool, ensuring reliable switching force and stability under high-pressure, high-flow conditions.
On-Board Electronics (OBE): The 4WRLE‘s built-in amplifier supports 24V DC power, simplifying wiring and enhancing electromagnetic interference (EMI) resistance.
Closed-Loop Position Feedback: An inductive position transducer on the main spool monitors displacement in real-time, drastically reducing hysteresis and optimizing linearity.
Comprehensive Flow Coverage: From precision control in Size 10 to massive flow throughput in Size 35, with operating pressures rated up to 350 bar.
