Pressure Relief Valve DBW30B2N5X/70Y6EG24N9K4E - Bosch Rexroth R900779316

Some consumers tolerate only a fraction of the system pressure yet run on the same power unit. This pilot-operated pressure relief valve caps pressure across a range of 4 to 70 bar while accepting up to 700 l/min.

Benefits

• Setting range of 4 to 70 bar, matched to consumers with a low permitted pressure.
• 700 l/min permitted flow, so the full delivery drains away without a pressure rise.
• Internal hexagon under a protective cap keeps the low limit secure.
• Pilot-operated seat valve with tight closing in the rest position.
• Maximum operating pressure of 350 bar as the body limit.
• 6.45 kg weight with connection diagram ISO 6264-10-17.

Application

Intended for coolers, filter housings, accumulator charging circuits and prefill lines with a low pressure rating. The concealed adjustment ensures the protection limit is not raised. During pauses the solenoid unloads the circuit, with NBR seals for HL hydraulic fluid.
