The Bosch Rexroth 04330710860000A-VSON-12U-G-00-A (R901106639) is a high-performance screw-in cartridge valve designed for hydraulic applications that require a pilot operated check function. This valve allows flow in one direction and blocks it in the reverse direction until pilot pressure is applied to open the poppet. It is specifically engineered to ensure stable operation under a maximum operating pressure of 350 bar (5076 psi) and can handle a maximum flow of up to 60 l/min (15.9 gpm), making it suitable for various hydraulic systems. The valve features a pilot ratio of 4:1, which means that the opening force at the pilot port is amplified, allowing for efficient operation even under high pressure conditions. The VSON model operates with an external pilot and does not come with a pressure presetting, offering flexibility for system integration. Its cavity conforms to Sun TA standards, ensuring compatibility with common industry practices. Constructed with NBR sealing material, the Bosch Rexroth VSON valve maintains integrity and prevents leaks even in demanding environments. The poppet type spool within this valve ensures reliable performance and durability over time. With its nominal flow capacity and robust design, this product is suitable for applications where precise control of hydraulic fluid is essential. Weighing approximately 0.32 kg, this compact unit does not add significant weight to the system while providing effective control of hydraulic functions using fluids such as HL or HLP types. As part of Bosch Rexroth's product family classification for pilot operated check valves that are designed to open with pilot pressure, this model exemplifies the company's commitment to quality and innovation in hydraulic components.
