FAQ

What does the spool symbol ‘CK13’ signify?

The spool symbol ‘CK13’ defines the flow paths in the valve’s different positions. It indicates a 3-position, 4-way valve where the center position blocks all ports (P, T, A, B), and the two actuated positions connect P to A and B to T, or P to B and A to T respectively.

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

This valve is rated for a maximum operating pressure of 350 bar (approximately 5075 PSI) and a nominal flow rate of 12 liters per minute (l/min).

Can the 24V DC solenoid be replaced or serviced separately?

Yes, the solenoid coil on Rexroth M-3SED valves is a modular component. It can be removed and replaced without opening the hydraulic circuit, which simplifies maintenance and reduces machine downtime.
