Pressure Relief Valve DBW10A2-5X/315-6EG24N9K4QMAG24V - Bosch Rexroth R901540832

A pump needs a firm pressure limit, and during idle phases the circuit should carry as little pressure as possible. The DBW10A2-5X/315 does both in a single component, limiting pilot-operated across 4 to 315 bar and switching to unloading through a built-on directional spool valve with a 24 VDC solenoid.

Benefits

• Setting range 4 to 315 bar, adjusted through an internal hexagon with protective cap that stays reachable once installed.
• Solenoid unloading via the built-on directional spool valve with 2 switching positions at 24 VDC supply voltage.
• Poppet seat design keeps leakage low in the closed state, permissible operating pressure up to 350 bar.
• 250 l/min flow at a valve weight of 4.74 kg in size 10.
• Connection diagram ISO 6264-06-09 for subplate mounting, wired through a 3-pole connector (2 + PE) according to EN 175301-803.
• FKM seals for hydraulic fluid of group HL.

Applications

In press, clamping and power unit hydraulics the valve caps system pressure at the set value and protects pump and piping against overload. Solenoid unloading takes pressure off the circuit between cycles, which saves drive power and limits heat input into the oil. It mounts on a subplate to ISO 6264-06-09 in circuits up to 250 l/min.
