Pressure Relief Valve DBW30B2N5X/50S6EG24N9K4R12V - Bosch Rexroth R901257473

A pressure stage built for 350 bar cannot be set cleanly at 20 bar. The DBW30B2N5X/50S6EG24N9K4R12V therefore uses a spring for 4 to 50 bar and keeps the size 32 relief flow of 650 l/min.

Benefits

• Adjustment range 4 to 50 bar, fine resolution at low pressure.
• 650 l/min relief flow despite the low pressure stage.
• Subplate mounting ISO 6264-10-17 in size 32.
• FKM seals for HL hydraulic fluid at elevated temperature.
• 7 kg, solenoid unloading on 24 V DC.

Application

It is used in return and back-pressure circuits and in cooling and filtration loops with high flow at low pressure. The low pressure stage protects heat exchangers and filter bowls that tolerate only a few bar. Maximum operating pressure of the valve itself is 350 bar.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW30B2N5X/50S6EG24N9K4R12V under material number R901257473. Data sheets RE 25802 and RE 25802-B show characteristic curves, installation dimensions and connection diagram. The spring for 4 to 50 bar separates this valve from the higher pressure stages of the same series.
