Pressure Relief Valve DBW20B2-5X/315S6SMG24N9K4B12V - Bosch Rexroth R900608715

Every hydraulic circuit needs one point where pressure is limited safely, and that point has to suit the fluid. The pilot-operated pressure relief valve DBW20B2-5X/315S6SMG24N9K4B12V uses FKM seals, covers a setting range of 4 to 315 bar and relieves up to 500 l/min through size 25.

Benefits

• Setting range 4 to 315 bar, adjusted through an internal hexagon with a protective cap.
• Up to 500 l/min relief flow in size 25 to port pattern ISO 6264-08-13.
• Pilot-operated poppet seat design, the main stage follows the small pilot stage.
• Solenoid at 24 VDC, two switching positions for unloading the circuit electrically.
• FKM seals and 6.06 kg, HL hydraulic fluid, subplate mounting.

Application

Pilot-operated pressure relief valves sit at the pump and define the maximum system pressure. The solenoid lets the machine stand unloaded without switching the pump off. FKM seals are meant for circuits in which oil temperature stays high over long shifts.
