Rexorth DBDS6K1X/190E Plug-In Relief Valve - Key Parameters

Rexroth DBDS6K1X/190E 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 to divert flow to the tank when a preset pressure is exceeded, thereby protecting system components.

Q2: What does the "/190E" suffix in the part number mean?

A:​ The /190Esuffix typically indicates that the valve is factory-set to a specific pressure, in this case likely 190 bar. The "E" may denote a particular production variant or engineering specification. The pressure can usually be readjusted within its rated range.

Q3: How is the pressure setting adjusted?

A:​ The pressure setting is manually adjustable. It is changed by turning an adjustment screw, which compresses an internal spring to set the desired opening (cracking) pressure. The adjustable range is typically 5 to 400 bar.

Q4: How is the valve installed?

A:​ It is a plug-in cartridge valve. It is installed by screwing it into a standard threaded cavity (typically M16 x 1.5) in a hydraulic manifold, valve block, or subplate, which allows for easy installation and replacement.

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 industrial and mobile hydraulic systems where reliable and compact pressure limiting is required.

Q6: Where can I find complete specifications?

A:​ For complete installation instructions, performance curves, and detailed technical data, please consult the official product documentation for order code R900769564.
