Pressure Relief Valve DB52F3-3X/315XUV - Bosch Rexroth R901009423

In large circuits the discharge capacity of the relief valve decides how safe the system is. The DB52F3-3X/315XUV in size 52 takes up to 2000 l/min and limits pressure to the value set, up to 315 bar.

Benefits

• 2000 l/min flow in size 52, pilot-operated design.
• Pressure adjustment range 3.9 to 315 bar on a lockable rotary knob with scale.
• Poppet seat design, which closes tightly at rest.
• Flange connection with 3 ports, hydraulic actuation.
• 26 kg, FKM seals for HL hydraulic fluid.

Applications

The valve protects power units of presses, steelworks equipment and test rigs against inadmissible pressure. The scale on the knob makes the setting traceable, while the lock prevents unauthorised adjustment. As a poppet valve it closes with little leakage, so pressure in the circuit holds even over long standstill periods.
