Rexroth DBDS6K1X/400V Plug-In Relief Valve - Key Parameters

Rexroth DBDS6K1X/400V Valve - FAQ

Q1: What is the main function of this valve?

A:​ This is a direct-acting, adjustable pressure relief valve. Its primary function is to limit the maximum pressure in a hydraulic circuit by opening and diverting excess flow to the tank when the preset pressure is reached, protecting system components.

Q2: How is the pressure setting adjusted?

A:​ The pressure setting is manually adjustable, typically within a range of 5 to 400 bar. It is adjusted by turning a screw on the valve, which compresses an internal spring to set the cracking pressure. The /400Vsuffix in the part number indicates the specific pressure setting variant.

Q3: How is the valve installed?

A:​ It is installed as a plug-in cartridge. It screws into a standard threaded cavity (typically M16 x 1.5) in a hydraulic manifold, valve block, or subplate, which simplifies installation and maintenance.

Q4: What are the key operating limits?

A:​ The maximum operating pressure is 400 bar. The typical maximum flow capacity is up to 30 liters per minute. It is designed for use in NG6 (CETOP 3) size systems.

Q5: What are the typical applications?

A:​ It is commonly used as a main system relief valve, a branch circuit relief valve, or a safety valve in various hydraulic systems for industrial machinery, mobile equipment, and more, where compact and reliable pressure limiting is required.

Q6: Where can I find complete technical data?

A:​ For installation dimensions, pressure-flow performance curves, and detailed specifications, please consult the official product documentation for order code R900438939.
