The Bosch Rexroth DBDS2K2X/200 (R900203852) is a mechanically actuated industrial hydraulic valve designed for high-performance applications, offering reliable pressure limitation to a preset value. This direct-actuated pressure relief valve is part of the product group ID DBD, intended for block design installations and serves as a system pressure limiter. The adjustment type allows for precise setting of system pressure via an external component.
In its default state, the valve remains closed until the pressure in main port P exceeds the threshold set by the compression spring, at which point ball 3 opens, allowing hydraulic fluid to flow into main port T. The DBDS2K2X/200 features a hexagon screw with a protective cap for adjustments and is capable of handling maximum operating pressures up to 350 bar with a maximum flow rate of 200 l/min.
Constructed with NBR seals, this screw-in cartridge valve accommodates hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. It showcases a robust design with two ports and various adjustment types available including hexagon with protective cap, rotary knob with scale, lockable rotary knob with scale, and hand wheel options for different operational needs.
The size 10 component series X valve ensures durability and consistent performance in demanding environments. The weight specifications and number of switching positions are not provided within this summary but are integral to understanding its full capabilities within its application context.

Function, section, symbol
Pressure valves of type DBD .. K are direct operated pressure relief valves to be installed in block designs. They are used for system pressure limitation. The system pressure can be set via the adjustment type (5).
In the initial position the valve is closed. Via control line (1) and ball (2), the pressure in the main port ① acts on the spring plate (3). If the pressure in the main port ① rises above the value set at the compression spring (4), the ball (2) opens and the hydraulic fluid flows into the main port ②.

p-qV characteristic curves
Notice:
The characteristic curves apply to output pressure = zero in the entire volume flow range and were measured without housing resistance.
General information
Hydraulic counter pressures in the main port ➁ (T) add 1:1 to the response pressure of the valve set at the adjustment.
Example:
Pressure adjustment of the valve due to spring preloading (item 4 on product description) pspring = 200 bar Hydraulic counter pressure in the main port ➁ (T): phydraulic = 50 bar⇒ Response pressure = pspring + phydraulic = 250 bar
