The Bosch Rexroth DR 10 K4-3X/200YM (R900438133) is a high-performance screw-in cartridge valve designed for efficient pressure reduction in hydraulic systems. This pilot-operated pressure reducing valve is part of the DR.K product family and is specifically engineered for block design installation. Its primary function is to moderate system pressure by allowing the user to set the desired secondary pressure via an adjustment rotary knob. Featuring a maximum operating pressure of 315 bar (4568 psi) and a nominal flow capacity, this valve ensures precise control over hydraulic fluid flow from main port A to B without restrictions in its normal position. The DR 10 K4-3X/200YM valve employs a poppet-type spool that responds to changes in pressure, maintaining a constant value set by the user through the spring mechanism. The valve's pilot oil supply is internal, while it requires an external pilot oil return, ensuring reliable operation and easy maintenance. It is equipped with NBR sealing material suitable for use with HL and HLP hydraulic fluids, which contributes to its durability and longevity under various operating conditions. Additionally, this model comes with multiple adjustment options including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale—providing versatility and security in setting pressures according to specific application requirements. The Bosch Rexroth DR 10 K4-3X/200YM valve's robust construction and meticulous design make it an essential component for applications requiring precise pressure regulation within hydraulic circuits. With its ability to maintain consistent performance even under high-pressure conditions, this valve stands out as a reliable solution for industrial hydraulic systems.
