FAQ;

1. 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).

2. 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

3. 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.

4. What pressure sensors work with 4WREE valves?
Rexroth’s HM series pressure sensors (e.g., HM18-1X/250-C-K35) or third-party sensors with 4-20 mA output are compatible for pressure feedback applications.

5. Can I add a position feedback sensor to a 4WREE valve?
Yes, optional position feedback sensors (inductive or potentiometric) can be installed to monitor spool position and enable closed-loop control.

34. What is the purpose of a bypass valve with 4WREE installations?
A bypass valve allows fluid to bypass the 4WREE during maintenance or emergency shutdowns, preventing system pressure buildup.
