FAQ:
1. What is the hysteresis of 4WREE valves?
Hysteresis is typically ≤3% of the full-scale control signal, ensuring precise and repeatable flow regulation.
2. What is the minimum operating pressure required for 4WREE valves?
The minimum operating pressure is 2 bar (29 psi) to ensure proper spool actuation and prevent cavitation.
3. How does temperature affect valve performance?
Operating temperatures between -20°C and +80°C (-4°F to +176°F) are optimal. Temperatures outside this range may reduce response time or damage seals and electronics.
4. What is the valve’s flow coefficient (Cv)?
Cv values range from 0.8 (NG 6) to 12.0 (NG 25), indicating the valve’s capacity to flow fluid at a given pressure drop (higher Cv = higher flow rate).
5. Can 4WREE valves be used in closed-loop control systems?
Yes, their low hysteresis and fast response make them ideal for closed-loop systems, paired with position or pressure feedback sensors.
Compatibility & Accessories
6. Are 4WREE valves compatible with Rexroth’s proportional amplifiers?
Yes, they are fully compatible with Rexroth’s VT series proportional amplifiers (e.g., VT-VSPA1, VT-VRPA1) for enhanced control and diagnostics.
