The Bosch Rexroth 04524503472000M-VBSN-16U-RS-4:1-20-200B& (R930081290) is a screw-in cartridge valve designed for hydraulic systems requiring precise control over load-holding and motion. This direct-acting counterbalance valve is part of the VBSN product family, characterized by a standard poppet type with differential area and counterclockwise adjustment for pressure settings. The valve operates at a maximum pressure of 350 bar (5076 psi) and can accommodate a maximum flow of 20 l/min (5.3 gpm). It features a pilot ratio of 4:1, ensuring stability in load control applications. The Bosch Rexroth R930081290 offers leakproof performance with its NBR sealing material and normally closed position when not actuated. The valve's cavity is compatible with Sun TA, allowing for ease of integration into various hydraulic circuits. Users can benefit from the adjustable pressure range provided by the counterclockwise adjustment direction, which allows for fine-tuning to meet specific application requirements. Designed with a poppet spool, this product ensures reliable operation in maintaining predetermined loads or controlling the lowering speed of loads in hydraulic systems. Its robust construction includes an adjustment option via a leak-proof hexagon socket screw, ensuring long-term durability and maintenance ease. This valve is particularly suitable for applications that require consistent performance in load-holding operations such as mobile hydraulics, industrial machinery, and material handling equipment. The combination of its high-pressure capability, precise adjustability, and compatibility with HL and HLP hydraulic fluids makes it an essential component for engineers seeking efficient and reliable hydraulic control solutions.
