Bosch Rexroth DR20-5-42-200YM Hydraulic Relief Valve

Bosch Rexroth DR20-5-42-200YM Hydraulic Relief Valve is a compact, industrial valve from the DR20 family designed to protect hydraulic circuits by maintaining a preset system pressure. As a DR20-5 variant, it functions as a pressure-relief valve that opens to vent excess flow back to the reservoir when the set pressure is reached, preventing overpressure that could damage pumps and actuators downstream. The DR20-5-5X/200YM family listings describe an adjustment range up to 200 bar, illustrating its suitability for demanding industrial systems, and the design supports subplate mounting for straightforward integration into standard manifolds and control blocks. Common applications include protection of hydraulic presses, machine tools, and automated equipment where reliable pressure limiting is essential. The valve is designed to operate with typical industrial fluids, including HL, HLP, HLPD, HVLP, HVLPD, and HFC, ensuring compatibility across Rexroth’s hydraulic circuits. The DR20-5-42-200YM designation identifies a specific configuration within Bosch Rexroth’s 200YM-class valves, offering a compact footprint and the robust construction expected from Rexroth components.
