Pressure Relief Valve DBW30B1-5X/315Y6EG12N9K4V/12 - Bosch Rexroth R978911198

Hot oil and a 12 V control supply meet more often than a catalogue suggests. This version of the DBW30B1-5X therefore pairs FKM seals with a 12 VDC solenoid and is set at a rotary knob from 4 to 315 bar.

Benefits

• 12 VDC solenoid for controls without a 24 V level.
• FKM seals, compatible with hot oil and fire-resistant fluids.
• Rotary knob for setting anywhere from 4 to 315 bar.
• 650 l/min in size 32, operating pressure up to 350 bar.
• 6.3 kg, subplate ISO 6264-10-17, symbol B in two switching positions.

Application

Its place is in power units whose control voltage comes from a 12 V source and whose oil runs warm in continuous duty. Those two traits together narrow the choice sharply, while hydraulically it remains the usual pilot-operated poppet valve of size 32. The subplate to ISO 6264-10-17 stays unchanged.
