Pressure Relief Valve DB52F2-3X/100U - Bosch Rexroth R900353049

This pressure relief valve protects a circuit with an adjustment range from 3.9 to 100 bar. Two ports are enough for installation, and flow reaches 2000 l/min at a maximum operating pressure of 315 bar. The setting element sits under a protective cap.

Benefits

• Two ports, which keeps piping at the size 52 flange simple
• Adjustment range 3.9 to 100 bar, internal hexagon under a protective cap
• Up to 2000 l/min flow at a maximum operating pressure of 315 bar
• Pilot-operated poppet seat valve, hydraulically actuated
• 27.59 kg weight, NBR seals for HL hydraulic fluid

Application

It is used for pump protection without remote adjustment. Because the setting is covered, the value stays unchanged after commissioning. Two ports shorten assembly time compared with a version carrying a separate pilot line.
