Rexroth Hydraulic Relief Valve DR20-5-52 315YM For Precise Pressure Reduction

The Bosch Rexroth DR20-5-5X/315YM (R900596754) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predetermined setting value. This mechanically actuated spool valve, featuring a B A spool symbol, is pilot-operated and capable of handling maximum pressures with exceptional precision.

The valve is suitable for subplate mounting and adheres to the ISO connection diagram standards. With its robust construction, the DR20-5-5X/315YM provides a seamless flow from channel B to channel A when in the rest position, thanks to its main spool insert. The pilot control valve comprises a pressure adjustment element that ensures stability and responsiveness in pressure regulation.

The main spool is balanced by the pressure in channel A and an adjustable spring mechanism that acts upon the pilot control valve, maintaining the desired reduced pressure with high accuracy.

The unit's external pilot oil return feature enhances performance by ensuring efficient operation of the control spool. Additionally, an optional check valve can be installed for free return flow from channel A to B, while a pressure gauge connection allows monitoring of the reduced pressure in channel A.

This Bosch Rexroth valve comes with multiple adjustment types including rotary knob options—both lockable and with scale—and sleeve with hexagon and protective cap for versatile application needs. The maximum operating pressure it can withstand is substantial, making it suitable for demanding hydraulic applications where precise pressure reduction is crucial.

Furthermore, its NBR seals are compatible with various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC. Overall, the Bosch Rexroth DR20-5-5X/315YM offers reliability and precision for industrial settings requiring meticulous control over hydraulic system pressures. Its design ensures long-lasting performance and adaptability to different system requirements.
