Pressure Relief Valve DBW10B2-5X/200US6EG24K4QMBG24R12 - Bosch Rexroth R900618313

Protecting a pump circuit does not end with pressure limitation, because during start-up and cycle pauses the pump should circulate unloaded. This pilot-operated seat valve in size 10 covers both duties, is set between 2 and 200 bar and relieves up to 250 l/min when it opens.

Benefits

• Adjustment range 2 to 200 bar, secured by an internal hexagon with protective cap.
• Seat valve design, the main poppet seals with low leakage up to the cracking pressure.
• 250 l/min relief flow with connection diagram ISO 6264-06-09.
• Solenoid actuation at 24 VDC and two switching positions for protection and unloading duty.
• 4.41 kg on subplate mounting, NBR seals for hydraulic fluid HL.

Application

The valve sits in the pressure line of a fixed displacement pump on presses, injection moulding machines and hydraulic test rigs. Subplate mounting keeps the piping off the valve, so it can be exchanged without breaking any lines. The solenoid lets the control switch the circuit to unloaded circulation whenever no force is required.
