Pressure Relief Valve DBW20B2-5X/240-6EG24N9K4E - Bosch Rexroth R901471422

Some machines prescribe a cut-off pressure that falls between the common steps. This 4 to 240 bar range meets such requirements without stretching the span all the way to the 350 bar valve limit. The pilot-operated poppet valve handles 400 l/min in size 25 and weighs 5.5 kg.

Benefits

• Setting range 4 to 240 bar for prescribed cut-off pressures
• Pilot-operated poppet valve, spool symbol B, two switching positions
• 400 l/min flow across the ISO 6264-08-13 subplate interface
• Internal hexagon with protective cap keeps the setting covered
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.5 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

The stage makes sense where an existing machine has to be protected at 240 bar as specified by its builder, for instance in presses and clamping equipment. Since the range stays below the 350 bar body limit, the spring works in a band that resolves well. The solenoid switches the circuit from the control system.
