FAQ

What does the spool symbol “CK13” mean on this valve?

The “CK” indicates a 3-position, spring-centered spool. In the center position, all ports (P, A, B, T) are blocked. When the solenoid is energized, it shifts the spool to direct flow. The “13” denotes the specific design series, in this case, series 1X.

Is the 24VDC solenoid coil (R901104847) replaceable?

Yes, the solenoid coil on Rexroth SED series valves is typically replaceable. You can unscrew the retaining nut on the end of the armature tube and slide the old coil off. Ensure the replacement coil matches the voltage (24VDC) and has the correct form factor.

What is the maximum operating pressure and flow rate for this valve?

The type code “…/350…” indicates a maximum operating pressure of 350 bar (approximately 5075 PSI) for ports P, A, and B. The nominal flow rate for a size 6 (NG6) valve like this is generally up to 80 liters per minute, depending on fluid viscosity.
