Pressure Relief Valve DBW30B2N5X/315-6EG24N9K4/12 - Bosch Rexroth R901320188

Many power units are designed around a limit of roughly 315 bar. This pilot-operated seat valve covers exactly that with a range of 4 to 315 bar, handles up to 650 l/min and weighs 6.4 kg.

Advantages

• Setting range 4 to 315 bar for the common rating of large power units
• Flow up to 650 l/min, maximum operating pressure 350 bar
• Subplate mounting to ISO 6264-10-17, so an existing unit can be swapped
• 24 VDC coil with two switching positions, symbol B
• Internal hexagon with protective cap, 6.4 kg, NBR seals for HL fluid

Application

The valve protects pump lines in presses, test rigs and hydraulic power units. Because the hole pattern is standardised, an existing valve can be replaced without reworking the manifold. Adjustment is made with a hexagon key and then closed off.
