Pressure Relief Valve DBW30B3N5X/350-6EG24N9K4V - Bosch Rexroth R900758239

Whether a power unit stays pressurised or vents when de-energised depends on the spool pattern of the mounted directional valve. This pilot-operated size 32 pressure relief valve uses symbol B for that and processes flow up to 650 l/min.

Benefits

• Spool symbol B on the mounted directional valve, two switching positions on two ports.
• Flow up to 650 l/min at a maximum operating pressure of 350 bar.
• Subplate mounting to ISO 6264-10-17, size 32.
• Supply voltage 24 VDC, Connector, 3-pole (2 + PE) to EN 175301-803.
• FKM seals for HL hydraulic fluid.
• Build DBW30B3N5X/350, weight 6.49 kg.

Application

For the safety assessment of a plant, the state the circuit assumes on loss of power is decisive. The spool pattern is therefore fixed together with the control design and can only be changed afterwards by replacing the complete valve.

Manufacturer

Bosch Rexroth lists this build under material number R900758239. The circuit diagram for symbol B, the setting ranges and the characteristic curves are given in data sheet RE 25802 and in the supplement RE 25802-B.
