Pressure Relief Valve DBW30B7N5X/50S6EG24N9K4R12 - Bosch Rexroth R901206171

Below 50 bar the spring stage decides how precisely a circuit can be protected. This pilot-operated seat valve is laid out for 4 to 50 bar while still relieving the full size 32 flow of 650 l/min. The body is rated for 350 bar operating pressure.

Benefits

• Adjustment range of 4 to 50 bar for circuits with a low limiting pressure
• 650 l/min relief capacity to the ISO 6264-10-17 interface
• Rotary knob with a scale, so the setting can be read at the valve
• Pilot-operated seat design with two ports
• Electrical unloading through the solenoid at 24 VDC
• Subplate mounting, NBR seals, weight 6.49 kg

Applications

Valves of this kind protect return, flushing and low-pressure circuits that move a lot of oil at little pressure. Prefill circuits of large cylinders work in the same window. The solenoid switches the circuit pressureless when required.

Manufacturer
