Rexroth Hydraulic Relief Valve DR20-5-52 200YM For Pressure Reduction 350 Max. Pressure

The Bosch Rexroth DR20-5-5X/200YM (R900597233) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predetermined setting. This mechanically actuated spool valve features:

• Pilot-operated design with NBR seal
• Compatibility with hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC
• Subplate mounting with ISO 5781-08-10-0-16 connection diagram
• Maximum pressure capacity with 300 max flow rate
• 2 switching positions
• Weighs 5.38 units for proper handling

The pressure reducing valve operates by allowing unrestricted flow from channel B to channel A via the main spool insert in its rest position. The pressure in channel A is balanced against a spring setting in the pilot control valve to achieve the desired reduced pressure, with an external pilot oil return ensuring continuous operation.

Optional features include:

• Check valve for free return flow from channel A to channel B
• Pressure gauge connection for monitoring reduced pressure
• Multiple adjustment types (rotary knob, sleeve with hexagon and protective cap)
• Lockable rotary knob with scale option
