FAQ

What is the significance of the “CK13” spool type in this M-3SED 6 valve?

The “CK13” designation refers to a specific spool configuration. It is a 3-position, spring-centered valve where the center position connects ports A and B to the tank (T) while blocking the pressure port (P). This is a ‘tandem center’ configuration, useful for unloading the pump in the neutral position.

What type of hydraulic fluid is recommended for use with this valve?

This valve is designed for use with mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. It can also be used with certain biodegradable fluids, but it’s crucial to consult the official Bosch Rexroth datasheet to ensure compatibility with your system’s fluid and operating temperatures.

Does this valve R900200031 come with the mating electrical connector?

This listing is for the valve itself as pictured. The N9K4 electrical connection requires a standard DIN EN 175301-803 (also known as Form A or DIN 43650) connector plug. This plug is a standard component and is typically sourced separately.
