4WRPEH Series High-Dynamic Direct-Operated Proportional Valves

Product Overview:

The 4WRPEH series is a high-performance range of direct-operated proportional directional valves designed for extreme dynamic response and control precision. Featuring Integrated Electronics (OBE) and Closed-Loop Spool Position Control, these valves provide exceptionally accurate flow regulation. The direct-acting design eliminates pilot-stage lag, making it the premier choice for high-speed, high-precision applications such as injection molding, testing equipment, and high-performance presses. Its robust construction ensures superior linearity and minimal hysteresis even in demanding environments.

Featured models include: 4WRPEH6C3B40L-3X/M/24A1, 4WRPEH10C3B100L-3X/M/24A1, and 4WRPEH6C4B24L-3X/M/24A1.

Key Technical Advantages:

• On-Board Electronics (OBE): Built-in 24V controller accepts direct analog commands, simplifying electrical integration and enhancing EMI resistance.

• Closed-Loop Position Control: An inductive position transducer monitors spool displacement, ensuring the flow output strictly follows the input signal.

• Rapid Response Dynamics: Specifically engineered for high-frequency cycles with short step response times, ideal for servo-hydraulic control.

• Optimized Flow Options: Precise coverage from 24 L/min up to 100 L/min to suit various actuator speed requirements.
