Pressure Relief Valve DBW20B2-5X/220-6EG24N9K4VE - Bosch Rexroth R901553390

A hydraulic system needs a defined upper limit for pressure, even when the actuator stalls. This pressure relief valve in poppet seat design takes on that job at 400 l/min and is adjustable from 4 to 220 bar.

Benefits

• pressure adjustment range 4 to 220 bar, set through an internal hexagon with protective cap
• 400 l/min maximum flow, 350 bar maximum operating pressure
• seat valve, pilot-operated, spool symbol B, two ports
• subplate mounting to ISO 6264-08-13, size 25
• FKM seals, 24 VDC solenoid actuation, CE conformity, 5.6 kg

Application

The valve sits in the main circuit of power units, presses and test rigs and protects pump and lines against overpressure. The poppet seat design closes tightly and limits leakage. The solenoid additionally allows the circuit to be unloaded.
