Pressure Relief Valve DB52F2-3X/100XU - Bosch Rexroth R901009418

The task of this valve is limiting system pressure to a set value. The adjustment range lies between 3.9 and 100 bar, the valve handles up to 2000 l/min and a maximum operating pressure of 315 bar. Its design is a pilot-operated poppet seat valve.

Benefits

• Adjustment range 3.9 to 100 bar, secured by an internal hexagon with protective cap
• Up to 2000 l/min flow in size 52
• Poppet seat design, which keeps leakage low in the closed state
• Flange connection with three ports, hydraulic actuation
• 27.14 kg weight, NBR seals for HL hydraulic fluid

Application

The valve protects pumps and actuators in large power units against overpressure. The protective cap over the internal hexagon prevents unintended adjustment during operation. The size 52 flange connection takes high flows without narrow cross sections.

Manufacturer
