Pressure Relief Valve DBW 30 B2-5X/200-6EG24N9K4/12 - Bosch Rexroth R978907091

A manifold rated for 200 bar wants a valve whose spring does not reach any higher in the first place. This version covers 4 to 200 bar, sits inside the block through its subplate interface and limits up to 650 l/min.

Advantages

• Setting range 4 to 200 bar, matched to circuits designed for 200 bar
• Flow up to 650 l/min in a housing released for 350 bar operating pressure
• Subplate mounting with two ports to ISO 6264-10-17
• Pilot-operated seat valve, 24 VDC coil, two switching positions
• Internal hexagon with protective cap, 6.3 kg, NBR seals for HL fluid

Application

The rating is used in feed and clamping circuits as well as in cooling and circulation loops carrying large volumes. A limited setting range stops anyone from driving the plant beyond what it was designed for. Inside the manifold the piping effort stays low.

Manufacturer

Bosch Rexroth carries the valve as R978907091 in the DB.10-30 product family. Curves and mounting position are described in the data sheet.
