Rexroth Pilot-Operated Pressure Relief Valve

Description

This is a DBW 20 series pilot-operated pressure relief valve from Bosch Rexroth, a leader in drive and control technology. This valve is designed to limit the pressure in a hydraulic system to a set maximum. It features a solenoid for unloading or for switching between two pressure levels, controlled by a 24V DC signal. Its robust construction ensures long-term reliability and precise operation.

FAQ

This code specifies the solenoid characteristics. '6E' indicates a solenoid-operated unloading function with a spring return. 'G24' means it operates on 24V DC. 'N9' refers to a concealed manual override, and 'K4' specifies the type of electrical connector, which is a standard DIN plug.

The nominal size '20' for this Rexroth valve corresponds to a maximum flow rate of approximately 300 liters per minute (l/min). Always consult the official datasheet for the exact performance curve based on your system's pressure and fluid viscosity.

This valve is typically compatible with mineral oil (HL, HLP) according to DIN 51524. For use with other fluids, such as synthetic or fire-resistant fluids, you must verify compatibility with the seal materials used in the valve by checking the full model code against the manufacturer's datasheet.
