Pressure Relief Valve DBW20B2-5X/130YS6SMG24N9K4B12E - Bosch Rexroth R901020413

The larger the flow to be discharged, the more the pressure rise across the valve matters. This size 25 version is rated for 450 l/min and limits pressure to a value set between 4 and 130 bar.

Benefits

• Rated flow of 450 l/min, designed for main circuits with a large oil demand
• Setting range of 4 to 130 bar at a permitted operating pressure of 350 bar
• Pilot-operated poppet seat stage with internal hexagon under a protective cap
• Solenoid unloading on 24 VDC across two switching positions, 3-pole connector to EN 175301-803
• Subplate mounting ISO 6264-08-13, NBR seals and a mass of 6.2 kg

Applications

The valve sits in power units of presses, plastics machinery and hydraulic stations with a high flow. During a pause the solenoid switches the circuit pressureless and relieves the drive. The valve runs on HL fluid.
