Pressure Relief Valve DBW30A2N5X/350YUS6EG24N9K4R12 - Bosch Rexroth R901228008

The DBW30A2N5X/350YUS6EG24N9K4R12 limits system pressure across the full range of 2 to 350 bar, which is the maximum operating pressure of size 32. Flow capacity reaches 650 l/min.

Benefits

• Adjustment range 2 ... 350 bar reaches the valve maximum operating pressure and allows a later pressure increase without changing the valve.
• Seat valve design with low leakage in the closed state, which matters during long holding periods.
• Internal hexagon with protective cap secures the pressure setting against accidental change.
• Flow capacity of 650 l/min in size 32 at a weight of 7 kg.
• Subplate mounting with 2 ports to ISO 6264-10-17.
• Electrical unloading at 24 VDC through a connector, 3-pole (2 + PE) to EN 175301-803.

Application

Valves like this go into presses, forging plant and test rigs working in the upper pressure band. Because the adjustment range reaches the maximum operating pressure, a later increase in machine output still leaves room in the setting. Solenoid unloading takes the pressure away for start up and idle phases.
