The Bosch Rexroth DB 6 K2-4X/200YV (R900486196) is a pilot-operated pressure relief valve designed for screw-in cartridge valve systems. This model is part of the DB.K product family, which is recognized for its reliability in maintaining system pressure limits. The valve operates with a maximum operating pressure of up to 315 bar and can handle a maximum flow rate of 200 l/min, making it suitable for a wide range of hydraulic applications. The valve features an Mx cavity and utilizes FKM sealing material to ensure durability and compatibility with various hydraulic fluids such as HL, HLP, HEES, and HEPG. The DB 6 K2-4X/200YV is equipped with a poppet type spool that responds to changes in system pressure, opening the connection from the main port A to B when the set pressure is exceeded. This action is controlled by an internal pilot oil supply and an external pilot oil return. Adjustment options for this model include a sleeve with hexagon and protective cap, allowing users to set the desired system pressure accurately. The design ensures that any counter pressures at main port A are added to the set pressure value. The product's compact size and component series X designation indicate that it conforms to standard dimensions for ease of integration into various hydraulic systems. With its robust construction and precise control capabilities, the Bosch Rexroth DB 6 K2-4X/200YV valve is an essential component for engineers looking to optimize their hydraulic systems' performance while ensuring safety through effective pressure management.

PRESSURE RELIEF VALVE DB 6 K2-4X/200YV

Pressure relief valve, pilot operated

Unpacked Weight: 0.2316 kg

Cartridge valve 4 pressure ratings 4 optional adjustment types:• Rotary knob• Sleeve with hexagon and protective cap• Lockable rotary knob with scale• Rotary knob with scale

Pressure valves type DB..K.. are pilot-operated pressure relief valves for block design installation. They are used for system pressure limitation. The system pressure can be set via the adjustment type (4).

In the initial position the valves are closed. The pressure in main port 1 acts on the spool (1). At the same time, pressure is applied to the spring-loaded side of the spool (1) via nozzle (2) and to the pilot poppet (6) via nozzle (3). If the pressure in main port 1 exceeds the value set at spring (5), the pilot poppet (6) opens. Hydraulic fluid flows from the spring-loaded side of the spool (1) via nozzle (3) and channel (7) into the main port 3. The resulting pressure drop moves the spool (1) and thus opens the connection from main port 1 to 2 while maintaining the pressure set at spring (5).

Die pilot oil return from the two spring chambers is effected externally, via main port 3.

Notice!

Counter pressures (main port 3) add up to the set pressure.
