The Bosch Rexroth MHDBV 40 K2-3X/420YMFL (R901225220) is a high-performance screw-in cartridge valve designed for precise pressure control in hydraulic systems. With a maximum operating pressure of up to 420 bar (6090 psi) and a nominal flow capacity, this pilot-operated relief valve ensures reliable operation and efficient fluid power management. The valve features a poppet-type spool, which maintains a normally closed position, contributing to system safety and preventing fluid leakage when the system is not in active use. The MHDBV 40 K2-3X/420YMFL is equipped with adjustment options including a grub screw with both internal and external hexagon interfaces and comes with a protective cap to safeguard the adjustment mechanism. This flexibility allows for easy tuning of the system pressure according to specific requirements without pressure presetting. The valve's cavity is FL Mx, indicating its compatibility with standardized cavities for ease of installation and maintenance. In terms of construction, the sealing material used is NBR (nitrile butadiene rubber), which provides good resistance to hydraulic fluids such as HL and HLP types. The pilot oil supply is internal while the pilot oil return is external, facilitating effective control over the relief function. Additionally, this model has a weight that ensures it can be integrated into various hydraulic circuits without adding significant mass. Overall, the Bosch Rexroth MHDBV 40 K2-3X/420YMFL cartridge valve stands out for its robust design and versatile application potential in controlling operating pressures within hydraulic systems while ensuring high levels of performance and reliability.
