BOSCH REXROTH DBW 30 BG2N52/160Y6EW230N9K4 R901298829

Rexroth DBW 30 Series Hydraulic Pressure Relief Valve

Description

This is a DBW 30 BG2N52/160Y6EW230N9K4 pilot-operated pressure relief valve from Bosch Rexroth. It is engineered to limit system pressure by diverting flow to the tank when the set pressure is reached. This model features a size NG30 subplate mounting design and includes an attached solenoid-operated directional valve for unloading or dual-pressure functions. It is a robust and reliable component for industrial hydraulic systems.

FAQ

What is the function of the solenoid on this DBW 30 pressure relief valve?

The solenoid controls a small directional valve mounted on top of the main relief valve. When energized, it can unload the system pressure to the tank or switch between two pre-set pressure levels, depending on the hydraulic circuit configuration.

What type of hydraulic fluid is compatible with the NBR seals (N code in the model number)?

The NBR (Nitrile) seals are compatible with standard mineral oil-based hydraulic fluids (HL, HLP). They are not recommended for use with synthetic fluids like phosphate esters (HFD). Always check fluid compatibility before installation.

How do I adjust the pressure setting on this valve?

The pressure setting is adjusted using the adjustment element, which is the knob/screw on the main valve body. Turning it clockwise increases the pressure setting, and counter-clockwise decreases it. It is crucial to have a pressure gauge in the system to accurately set and monitor the pressure. The maximum adjustable pressure for this model is 160 bar.
