The Bosch Rexroth 04592603572000M-VBST-12A-4:1-20-200B-OR (R930081332) is a screw-in cartridge valve designed for precise hydraulic control in various applications. This model features a vented guided poppet type from the VBST product family, ensuring reliable performance in maintaining load control and providing hose burst protection. It operates with a maximum pressure of up to 350 bar (5076 psi) and can handle a maximum flow of up to 20 l/min (5.3 gpm), suitable for systems requiring high-pressure thresholds. The valve is configured with an NBR sealing material that offers good resistance to hydraulic fluids, such as HL and HLP types, enhancing its durability and longevity under challenging conditions. The adjustment direction is clockwise, and it comes with a leakproof hexagon socket screw for secure installation within the Cavity CAAC. With an external pilot operation, the valve ensures stable load holding thanks to its pilot ratio of 4:1. This model is equipped with ports number 12A, signifying its interface design which allows for seamless integration into hydraulic circuits. The pressure setting can be adjusted within the specified range, providing flexibility for various application requirements. Additionally, it features pressure presetting capabilities that simplify setup procedures. The VBST-12A valve's poppet design ensures minimal leakage and maintains stability in the system by preventing unintended motion caused by external forces. Its normally closed position indicates that the valve blocks flow when not actuated, which is essential for safety in many hydraulic applications. Overall, the Bosch Rexroth R930081332 cartridge valve is engineered for precise load control in complex hydraulic systems where high-performance counterbalance solutions are required. Its robust construction and adjustable features make it a versatile component suitable for a wide range of industrial applications.
