Pressure Relief Valve DBW 20 B2-5X/315-6EG24N9K4V/12=CSA - Bosch Rexroth R978033030

Protection of a large pump depends on the relief capacity of the pressure relief valve. This pilot-operated seat valve in size 25 passes up to 500 l/min away, holds 350 bar maximum operating pressure and is fitted with FKM seals.

Benefits

• 500 l/min relief capacity through the ISO 6264-08-13 interface
• 350 bar maximum operating pressure in size 25
• FKM seals in operation with HL hydraulic fluid
• Seat valve design, which keeps leakage low in the closed state
• Electrical unloading through the mounted solenoid at 24 VDC
• Internal hexagon with a protective cap over the adjustment
• 5.3 kg on subplate mounting, so a swap leaves the piping untouched

Technical data

Applications

It protects pump circuits in presses, hydraulic power units and test rigs delivering up to 500 l/min. The solenoid lets the circuit run pressureless during breaks without stopping the pump. The protective cap over the internal hexagon holds the setting during operation.
