Product Overview
▔▔
The 4WRTE16W8 is engineered for systems that demand extreme accuracy, fast response times, and high flow capacities. It bridges the gap between standard industrial valves and high-end servo valves by utilizing specialized electrical position feedback.
Key Advantages
▔▔
- Integrated Electronics (OBE): The On-Board Electronics ensure precise control signal processing right on the valve, reducing external wiring complexity and electrical interference.
- High Dynamic Response: Capable of switching flow positions in milliseconds, making it perfect for rapid-cycle machinery.
- Position Feedback: Continuous monitoring of the valve spool position guarantees consistent performance even under shifting pressures.
- Fail-Safe Operation: Features automatic safety positioning if power or control signals are unexpectedly lost.

FAQ
▔▔
Q1: What is the main difference between a standard proportional valve and this servo-proportional valve?
A: Standard proportional valves control flow roughly based on current. This servo-proportional valve uses an internal sensor to constantly measure the exact physical location of the spool. It self-corrects on the fly, offering much higher precision and faster response times.
Q2: Why does the 4WRTE16W8 require a 24V supply if the control signal is only 10V?
A: The 24V supply powers the internal On-Board Electronics (OBE) and the powerful solenoids that drive the pilot stage. The 10V signal is purely a command instruction telling the valve how far to open.
