The Bosch Rexroth DR 10 K5-3X/200YMV (R900438117) is a screw-in cartridge valve designed as a pilot-operated pressure reducing valve for block design installation. This product is part of the DR.K product family, which falls under the category of pressure valves specifically engineered for reducing system pressure. It operates with a maximum operating pressure of 315 bar (4569 psi) and can handle a maximum flow rate of 200 liters per minute (52.8 gallons per minute). The DR 10 K5-3X/200YMV valve features a cavity Mx and utilizes FKM as the sealing material, ensuring compatibility with various hydraulic fluids such as HL, HLP, HEES, and HEPG. The normally open valve allows unrestricted flow from main port A to B in its initial position. When the secondary pressure exceeds the set value, the pilot poppet opens, allowing hydraulic fluid to flow and adjust the main spool to maintain constant pressure at port B. This model includes an internal pilot oil supply and an external pilot oil return mechanism. The poppet type spool within this unit ensures precise control over hydraulic systems. Adjustment options for setting the secondary pressure include a sleeve with hexagon and protective cap. The DR 10 K5-3X/200YMV is designed with attention to detail to ensure reliability in maintaining system pressures within hydraulic applications. Its robust construction and ability to work under high-pressure conditions make it suitable for a wide range of industrial applications where precise pressure reduction is required.

Pressure valves type DR 10 K.. are pilot-operated pressure reducing valves for block design installation. They are used for reducing a system pressure. The secondary pressure is set via the adjustment type (4).

In initial position, the valves are open. Hydraulic fluid can flow from main port 2 to 1 without restrictions. The pressure in main port 1 acts simultaneously at main spool (1) and via the nozzle (2) at the spring-loaded inside of the main spool (1). Similarly, it acts via nozzle (7) on the pilot poppet (8). If the pressure in main port 1 exceeds the value set at spring (5), the pilot poppet (8) opens. Hydraulic fluid flows from the chamber of spring (3) via the nozzle (7), the pilot poppet (8) and the spring chamber (6) into main port 3. The main spool (1) assumes its control position and keeps the value in main port 1 set at the spring (5) constant.

The pilot oil return from the spring chamber (6) is always realized externally via main port (3).

Notice!

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