Bosch Rexroth DBDS 20 G 1X/200 direct-operated pressure relief valve
Bosch Rexroth DBDS 20 is a direct-operated pressure relief valve designed to protect hydraulic systems by limiting maximum pressure. The DBDS 20 series is widely used in industrial, marine, offshore, and heavy-duty hydraulic power units where reliable over-pressure protection is critical. Manufactured by Bosch Rexroth (Made in India), these valves are known for stable pressure control, rugged construction, and long service life.
The DBDS 20 G1X/200 and DBDS 20 K1X/200 variants support threaded G1 connections and adjustable pressure settings up to 200 bar, with versions available up to 315 bar. Solenoid-operated variants (DBDSOL 20) allow remote unloading or switching functions.
