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. Specifications Manufacturer: Bosch Rexroth Type: DBW 30 (Pilot-operated pressure relief valve) Size: NG30 Mounting Pattern: ISO 6264 Maximum Pressure Setting: 160 bar Solenoid Control: 230V AC, 50/60Hz Solenoid Coil Part Number: R900071030 Seals: NBR (for mineral oil based fluids) Connection: Subplate mounting Label Info MNR: R901298829 Model: DBW 30 BG2N52/160Y6EW230N9K4 FD: 30814 Application Ideal for use in general industrial machinery, presses, injection molding machines, and any hydraulic circuit requiring reliable overpressure protection with an electrical unloading function. Country of Origin Made in Germany CO2 Impact By purchasing this pre-owned item, you are helping to avoid the emission of approximately 52 kg of CO2, which is equivalent to driving a car for 260 km. This promotes a circular economy and reduces industrial waste. Availability This unit is in stock and ready for immediate dispatch. Order now from profideals for expert support and fast delivery. 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.
