Pressure Relief Valve DBW30A2-5X/100Y6EG24N9K4/12 - Bosch Rexroth R978919292

A circuit with low working pressure but a large flow rate needs a spring for the lower band and a high relief capacity at the same time. This pilot-operated seat valve in size 32 covers 4 to 100 bar and passes up to 650 l/min.

Benefits

• Adjustment range of 4 to 100 bar, so the scale spreads across the low pressure band in use
• 650 l/min relief capacity through the ISO 6264-10-17 interface in size 32
• 350 bar maximum operating pressure on the body
• Spool symbol A with two switching positions and two ports
• Electrical unloading through the mounted solenoid at 24 VDC
• Internal hexagon with a protective cap, 6.5 kg on subplate mounting

Technical data

Applications

It protects circulation and pre-fill circuits, cooling circuits and the low pressure stage of large presses, where a lot of oil moves at modest pressure. The solenoid takes the circuit pressureless during breaks. The protective cap holds the setting during operation.
