The Bosch Rexroth 043307105700000-VSON-12A-G-00 (R901106634) is a high-quality screw-in cartridge valve designed for hydraulic applications requiring a pilot-operated check function. This valve allows free flow in one direction and blocks flow in the reverse direction until pilot pressure is applied to open the check. It features a maximum operating pressure of 350 bar (5076 psi) and can handle a maximum flow of 120 l/min (31.7 gpm), making it suitable for various hydraulic systems. The VSON-12A-G-00 valve is part of Bosch Rexroth's VSON product family, which is known for its reliability and performance in controlling the flow of hydraulic fluid. Its cavity type is CAAC, which conforms to industry standards for ease of integration into existing systems. The sealing material used is NBR, providing good resistance to oil and other hydraulic fluids typically used in such systems, including HL and HLP types. With a pilot ratio of 4:1, this valve ensures precise control over the hydraulic flow, offering stability and security in operations that demand tight control over movement or load-holding. The product comes without pressure presetting, allowing users to adjust it according to their specific requirements. The poppet-type spool within this model ensures a tight seal when closed, contributing to the efficiency and safety of the system it's integrated into. With its nominal weight of 0.3 kg, it adds minimal mass to the system while providing essential functionality. In summary, the Bosch Rexroth VSON-12A-G-00 valve offers robust performance for applications requiring pilot-operated check capabilities with external pilot operation. Its design ensures reliability and precision for systems needing controlled flow direction under varying pressures and flows.
