Pressure Relief Valve DBW20A2-5X/315XYUS6SMG24N9K4B12 - Bosch Rexroth R901546021

Alongside pressure stage 315, the type code of this build shows the additions X and Y, which concern the routing of the pilot oil. As a pilot-operated size 25 pressure relief valve it limits pressure at flow up to 500 l/min.

Benefits

• Build DBW20A2-5X/315XYUS with spool symbol A.
• Flow up to 500 l/min, maximum operating pressure 350 bar.
• Subplate mounting to ISO 6264-08-13 in size 25.
• Electrical unloading from 24 VDC through the mounted directional valve.
• NBR seals, HL hydraulic fluid.
• Two switching positions on two ports, weight 6.9 kg.

Application

Which variant of the type code is needed follows from the circuit diagram of the power unit and from how pilot oil is fed in and led away. For a replacement in an existing plant the designation should therefore match the installed valve in full.
