Pressure Relief Valve DBW20B2-5X/350-6EG24N9K4V/12=CSA - Bosch Rexroth R900248578

When a plant works close to its maximum operating pressure, the adjustment range of the relief valve has to reach that far. This pilot-operated seat valve in size 25 covers 4 to 350 bar and passes up to 500 l/min while doing so.

Benefits

• Adjustment range of 4 to 350 bar, matching the maximum operating pressure of 350 bar
• 500 l/min relief capacity through the ISO 6264-08-13 interface
• Seat valve design, which keeps leakage low in the closed state
• FKM seals for operation with HL hydraulic fluid
• Electrical unloading through the mounted solenoid at 24 VDC
• Internal hexagon with a protective cap, 5.28 kg on subplate mounting

Applications

It protects presses, clamping circuits and test rigs whose working pressure sits just below the maximum operating pressure. In a fault the full delivery flow of up to 500 l/min is passed away. The protective cap over the internal hexagon secures the setting against accidental change.
