Pressure Relief Valve DBW20A2-5X/315-6EG24N9K4E - Bosch Rexroth R901265673

A nominal pressure of 315 bar is a fixed figure in pump and cylinder catalogues, and this setting range of 4 to 315 bar reproduces it exactly. The valve carries spool symbol A and works pilot-operated in poppet seat design. Up to 400 l/min discharge across the ISO 6264-08-13 subplate interface, and the mass is 5.38 kg.

Benefits

• Setting range 4 to 315 bar, matched to the 315 bar nominal pressure class
• Spool symbol A with two switching positions and two ports
• Pilot-operated poppet valve in size 25 rated for up to 400 l/min
• Internal hexagon with protective cap, subplate mounting to ISO 6264-08-13
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.38 kg mass, NBR seals for HL hydraulic fluid

Application

The stage is needed in circuits whose pumps and cylinders are rated for 315 bar, for instance in presses and hydraulic drives of heavy machinery. The permissible operating pressure of 350 bar still leaves room for pressure peaks. The solenoid switches the circuit from the machine control.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20A2-5X/315-6EG24N9K4E under material number R901265673. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Watch for spool symbol A, which differs from the B versions in the circuit diagram.
