Rexroth Hydraulic Relief Valve DR20-5-52 100y Adjustable Pressure Element

The Bosch Rexroth DR20-5-5X/100Y (R900597198) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a set value. It features a spool symbol B A and allows for maximum pressure within its product group.

This mechanically actuated valve comes with subplate mounting and an ISO connection diagram, ensuring easy integration into various hydraulic systems. The valve is equipped with NBR seals and is compatible with multiple hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.

The DR20-5-5X/100Y operates as a pilot-operated pressure reducing valve that is controlled from the secondary circuit, consisting of a main valve with a main spool insert and a pilot control valve with an adjustable pressure element. In its rest position, the valve permits unrestricted flow of hydraulic fluid from channel B to channel A. The applied pressure in channel A balances against the preset spring tension to achieve the desired reduced pressure level.
