Rexroth Pilot-operated Pressure Relief Valve 100 bar 24VDC

Description

The Rexroth DBW 20 B2-52/100-6EG24N9K4 is a high-quality pilot-operated pressure relief valve, engineered for precise and reliable pressure control in industrial hydraulic systems. This valve is designed to limit the system pressure by diverting flow to the tank when the set pressure is reached. The integrated 24V DC solenoid provides the functionality for electrical unloading or switching between pressure settings, enhancing system flexibility and control.

FAQ

Question?
What is the function of the solenoid on this DBW 20 pressure relief valve?

The 24V DC solenoid allows for electrical actuation. When energized, it typically unloads the main valve, causing the system pressure to drop to a minimum, or it can switch between two pre-set pressure levels depending on the circuit design.

Question?
What does the '100' in the type code DBW 20 B2-52/100-6EG24N9K4 signify?

The '100' indicates the maximum pressure setting of the valve in bar. This particular valve can be adjusted to relieve pressure at any point up to a maximum of 100 bar (approximately 1450 PSI).

Question?
Is it possible to adjust the pressure setting on this valve manually?

Yes, the pressure setting is adjustable. The adjustment is typically made via a screw or knob on the main stage of the valve, allowing for fine-tuning of the relief pressure within its specified range.
