The Bosch Rexroth 043310008503000-VSOA-10A-03 (R901117420) is a high-performance screw-in cartridge valve designed for efficient control in hydraulic systems. This pilot-operated check valve, belonging to the VSOA product family, is tailored to facilitate pilot-to-open operations. It features a robust poppet type spool and is constructed to handle a maximum operating pressure of up to 350 bar (5076 psi), ensuring reliable performance under demanding conditions. The valve is capable of managing a maximum flow of 100 l/min (26.4 gpm), which allows for substantial fluid throughput. The 043310008503000-VSOA-10A-03 valve offers versatility through its external pilot operation and comes without pressure presetting, allowing users to customize the pressure settings according to their specific application needs. It employs NBR (Nitrile Butadiene Rubber) as sealing material, which provides good resistance to oils and hydraulic fluids such as HL and HLP types, contributing to the valve's durability and longevity. Designed with a nominal flow rating, this model ensures consistent performance and can be integrated into various hydraulic circuits thanks to its standard CAAN cavity. The pilot ratio stands at 1:3, which contributes to the valve's responsive control dynamics. With its straightforward screw-in cartridge design, installation and maintenance are simplified, reducing downtime and facilitating system integration. This Bosch Rexroth valve is characterized by its lack of pressure presetting and reliance on an external pilot for operation. Weighing just 0.3 kg, it doesn't add significant mass to the system it serves, making it an ideal choice for applications where space and weight are critical factors. Its precise engineering ensures that it meets the rigorous demands of industrial applications requiring controlled motion or load holding capabilities.
