Pressure Relief Valve DBW30B2N5X/160-6EG24N9K4E - Bosch Rexroth R901012917

Many clamping and feed circuits work between 150 and 180 bar, where a narrow scale makes setting easier. This pilot-operated pressure relief valve covers 4 to 160 bar and discharges up to 580 l/min through its subplate connection.

Benefits

• Setting range of 4 to 160 bar, so the working point can be hit more precisely than with a widely spread scale.
• Internal hexagon under a protective cap holds the adjusted value.
• Pilot-operated seat valve with tight closing in the rest position.
• Maximum operating pressure of 350 bar as the body limit.
• Electrical unloading at 24 VDC across two switching positions.
• 6.5 kg weight at 580 l/min maximum flow.

Application

A fit for clamping hydraulics, feed drives and machine tools at moderate process pressure. The secured adjustment makes every station hold the same value. The solenoid lets the circuit idle pressureless between cycles, with NBR seals for HL hydraulic fluid.
