This model is part of the VBSN product family, which is characterized by standard poppet type differential area valves with counterbalance capabilities. The valve operates at a maximum pressure of 350 bar (5076 psi) and can handle a maximum flow of 120 liters per minute (31.7 gallons per minute), making it suitable for systems that require high-pressure performance. The valve features an NBR sealing material and utilizes a CAAC cavity. It has adjustable pressure settings, which can be altered by turning the adjustment options clockwise. This particular model comes with leakproof hexagon socket screws ensuring secure and reliable operation without the risk of fluid leakage. The pilot ratio for this valve is 4:1, indicating its responsiveness and precision in balancing loads. This specific model has a normally closed normal position, with direct acting pilot control that provides immediate response to changes in pressure or flow. The nominal flow rate ensures consistent operation, while the preset pressure setting adds an element of convenience to the installation process. The VBSN-12A series valve's spool design features a poppet type mechanism that contributes to its efficient function and robust performance. Weighing in at just 0.2 kilograms, it is relatively lightweight for its class yet durable enough to withstand demanding conditions. Overall, the Bosch Rexroth R930081269 cartridge valve is engineered for reliability and optimal control in hydraulic systems where counterbalance functions are required, providing stability and safety across various applications without compromising on performance.
