Pressure Relief Valve DB52F2-3X/315U - Bosch Rexroth R900453821

At flows reaching 2000 l/min the discharge cross section decides how far pressure overshoots when the valve opens. The pilot-operated DB52F2-3X/315U is sized for this in size 52 and limits pressure across a range of 3.9 to 315 bar.

Benefits

• 2000 l/min flow through the size 52 flange connection
• Pressure adjustment range 3.9 to 315 bar, set through an internal hexagon with protective cap
• Poppet seat design for tight closing below the set pressure
• Pilot-operated with hydraulic actuation, 2 ports and 2 switching positions
• 27.45 kg, NBR seals for HL hydraulic fluid

Applications

Valves of this class protect pump stations, press cylinders and large hoists against impermissible pressure. On opening, oil flows from pressure port P to tank port T. After adjustment the protective cap secures the setting against accidental turning.

Manufacturer

Bosch Rexroth lists the valve under material number R900453821. In the type code, 315U states the upper end of the adjustment range together with the design of the adjustment element.
