FAQ

What is the function of the 7X series designation in the type code LC 40 DR40E7X/?

The “7X” indicates the component series, which is a version identifier used by Bosch Rexroth. It signifies a specific design generation with defined technical features and dimensions. When replacing a part, it is crucial to match the series or consult documentation for compatibility with newer series.

Is the solenoid included with this valve cover insert?

No, this product listing is for the mechanical insert assembly only, which includes the valve spool, spring, and seal as pictured. The corresponding electrical solenoid required for operation must be purchased separately.

What type of hydraulic fluid is compatible with the seals included in this kit?

This insert is typically fitted with NBR (Nitrile) seals, making it suitable for standard hydraulic fluids based on mineral oil (HL, HLP) according to DIN 51524. For use with synthetic fluids, you must verify seal compatibility and potentially use a variant with FKM (Viton) seals.
