Pressure Relief Valve DBW30A7-5X/200S6EG24N9K4R12 - Bosch Rexroth R900617939

The pilot stage of this valve works as a seat valve that closes tightly at rest and only opens the circuit to tank once the set value is exceeded. The range runs from 4 to 200 bar, and up to 650 l/min are relieved in size 32.

Benefits

• Seat valve design with low leakage in the closed state
• Adjustment range of 4 to 200 bar at a maximum operating pressure of 350 bar
• 650 l/min relief capacity to the ISO 6264-10-17 interface
• Rotary knob with a scale, so the setting stays readable
• Electrical unloading through the solenoid at 24 VDC, spool symbol A
• Subplate mounting, NBR seals for HL hydraulic fluid, weight 7 kg

Applications

The valve protects pump and consumer circuits where leakage over long holding times is a nuisance, for instance on clamping cylinders and holding circuits. The tight seat design holds pressure without the pump having to top it up constantly. When needed the solenoid makes the circuit pressureless.
