Benefits

• Spool symbol A combined with a setting range of 4 to 250 bar
• Flow up to 400 l/min across the ISO 6264-08-13 subplate interface
• Pilot-operated poppet valve in size 25, maximum operating pressure 350 bar
• Internal hexagon with protective cap for a permanently fixed pressure stage
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.34 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

The valve goes into series power units whose hydraulic diagram specifies symbol A and which are rated at 250 bar. The pilot-operated design keeps pressure stable even when the pump discharges fully across the valve. The solenoid switches the circuit independently of the pressure setting.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20A2-5X/250-6EG24N9K4E under material number R901185726. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data.
