The Bosch Rexroth 045244038620000-VBSN-12U-RS-4:1-20 (R930006116) is a high-performance screw-in cartridge valve designed for hydraulic systems requiring reliable load holding and controlled motion. This counterbalance valve is of the standard poppet type with a differential area and features a counterclockwise adjustment mechanism. The valve has a maximum operating pressure of up to 350 bar (5076 psi) and can handle maximum flow rates of 120 l/min (31.7 gpm), making it suitable for a wide range of applications. Equipped with an NBR sealing material, the 045244038620000-VBSN-12U-RS-4:1-20 ensures leakproof performance and is compatible with hydraulic fluids such as HL and HLP. It has an adjustable pressure range, which can be finely tuned via a leakproof hexagon socket screw, providing precise control over the system's operation. This model has been designed to fit into the Sun TA cavity, ensuring easy integration into existing hydraulic systems. Its direct acting pilot offers responsive control, while the normally closed poppet provides a secure shutoff when the valve is not activated. The pilot ratio of 4:1 allows for consistent operation under varying loads. The Bosch Rexroth counterbalance valve is particularly useful in applications where smooth motion control and load holding are critical, such as in mobile equipment, lifting devices, and industrial machinery. With its robust construction and precise adjustability, this product ensures efficiency and safety in demanding hydraulic circuits. The weight of this component is optimized for its function without compromising on durability or performance.
