Pressure Relief Valve DBW30B3-5X/200YS6EG24N9K4R12 - Bosch Rexroth R900910295

Two ports are enough because the valve sits in a bypass to the pressure line and only opens the path to tank once the set value is exceeded. The range runs from 4 to 200 bar and the relief capacity is 650 l/min.

Benefits

• Two ports, so the valve is fitted as a bypass to the pressure line
• 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
• Lockable rotary knob with a scale, seat design in the pilot stage
• Electrical unloading through the solenoid at 24 VDC
• Subplate mounting, NBR seals for HL hydraulic fluid, weight 6.31 kg

Applications

It is installed in the pressure line of a pump in power units of presses, injection moulding machines and test rigs. As long as the circuit stays below 200 bar the valve remains closed and causes no bypass loss. Once pressure rises above the set value it passes the delivery flow to tank.
