Pressure Relief Valve DBW20B2-5X/110S6SMG24N9K4B12E - Bosch Rexroth R901386384

A main line carrying 400 l/min can only be protected economically by a pilot-operated pressure stage. This size 25 valve limits pressure to a value set between 4 and 110 bar and its unloading solenoid additionally switches the circuit to pressureless circulation.

Benefits

• Setting range of 4 to 110 bar for a fine preselection in the lower pressure band
• Rated flow of 400 l/min at a permitted operating pressure of 350 bar
• Solenoid unloading on 24 VDC across two switching positions
• Poppet seat design, which keeps leakage low in the closed position
• Subplate mounting to ISO 6264-08-13, NBR seals and a mass of 6.16 kg

Technical data

Applications

The valve protects main circuits of power units, presses and test rigs working in the lower pressure band. The solenoid lets the installation start without load or relax during a pause. HL is the intended hydraulic fluid.
