Pressure Relief Valve DBW52AP2-3X/315XU6EG24N9K4 - Bosch Rexroth R901119479

Which state a power unit should assume when de-energised decides the form of the solenoid valve in the pilot stage. The DBW52AP2-3X carries spool symbol A, limits pressure to a setting of 4 to 315 bar and passes up to 2000 l/min.

Benefits

• Spool symbol A defines the de-energised rest position, which has to match the safety concept of the plant.
• Adjustment range 4 to 315 bar at the internal hexagon, protective cap against tampering.
• Flow up to 2000 l/min in size 52 with subplate mounting.
• Solenoid at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803, two switching positions.
• Pilot-operated seat valve, weight 28.5 kg, NBR seals, hydraulic fluid class HL.

Applications

The valve protects power units in presses, injection moulding machines and steelworks equipment. It usually sits straight on the tank lid and also handles unloaded start-up. Two ports are enough because oil goes from the pressure port directly into the tank.
