Pressure Relief Valve DBW20B2-5X/140-6EG24N9K4E - Bosch Rexroth R901036511

The cylinder does not always dictate the pressure limit, often it is piping, hoses or fittings of an older design. A setting range of 4 to 140 bar keeps the circuit below such limits while the valve discharges the full 400 l/min. The subplate interface follows ISO 6264-08-13.

Benefits

• Setting range 4 to 140 bar, matched to limited line pressure ratings
• Flow up to 400 l/min in size 25
• Pilot-operated poppet valve with spool symbol B and two switching positions
• 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
• 5.36 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

A typical case is a modernised existing machine whose piping was not replaced and whose pressure rating is therefore fixed. The limited setting range prevents the cut-off pressure from being turned beyond what the line is rated for. The solenoid switches the circuit without changing the stage.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/140-6EG24N9K4E under material number R901036511. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Document the pressure rating of piping and fittings before setting the valve.
