FAQ:
Spool Type (C4)
The C4 spool is a zero-overlap (critical center) spool with servo-valve quality. This design provides high linearity and fast response, ideal for closed-loop control applications. The "B24L" indicates a specific flow gain characteristic (24 L/min with linear characteristic "L").
Control & Feedback (/Z4)
The /Z4 suffix indicates a differential ±10 V DC voltage input for the command signal. The valve features integrated LVDT position feedback, enabling full closed-loop control of the spool position. Crucially, this valve does NOT have integrated on-board electronics (OBE); it must be used with an external servo amplifier.
High Dynamic Performance
As a direct-acting valve with a servo-type spool, the 4WRPH series offers high frequency response (typically > 100 Hz) and fast step response. It is suitable for applications requiring servo-like performance with the robustness of a proportional valve.
Fail-Safe Behavior
This valve is single-side actuated (single proportional solenoid with spring return). In the event of power failure, the spring returns the spool to a defined 4/4 fail-safe position (typically all ports blocked or P to B, A to T, depending on spool configuration).
Critical Installation Notes
External Amplifier Required: You must pair this valve with an external servo amplifier (e.g., Rexroth VT-VRRA1-527-20/V0) to provide power and process the LVDT feedback signal.
Cleanliness: Maintain high oil cleanliness (recommended ISO 4406 18/16/13 or better) due to the sensitive servo-type spool and sleeve assembly.
Voltage Supply: Ensure a stable 24V DC supply (18...30 VDC) with low ripple to avoid noise in the control signal.
