Pressure Relief Valve DBW30B2N5X/315-6EG24N9K4/12=CSA - Bosch Rexroth R900771642

The pressure in a hydraulic circuit has to be limited to a set value, and between two working strokes the pump should run unloaded. The pilot-operated pressure relief valve DBW30B2N5X/315-6EG24N9K4/12=CSA in size 32 covers both duties at a flow of up to 650 l/min.

Benefits

• Adjustment range 4 to 315 bar through an internal hexagon with a protective cap, which keeps the setting safe from accidental changes.
• Up to 650 l/min across two ports, subplate mounting to port pattern ISO 6264-10-17.
• Pilot-operated poppet design, the pressure stage shuts off tightly.
• Electrical unloading at 24 VDC, two switching positions to symbol B through a 3-pole connector (2 + PE) according to EN 175301-803.
• Maximum operating pressure 350 bar with NBR seals for HL hydraulic fluid.
• 6.4 kg weight in size 32.

Application

Relief valves of this series protect power units, presses and clamping systems against excess pressure and route the pump flow to tank during idle periods. Electrical unloading saves drive power and keeps the oil temperature down, because the flow does not work against full pressure all the time. The adjustment range from 4 to 315 bar covers clamping circuits at low pressure as well as pressing circuits.
