The Bosch Rexroth ZDB6VB2-4X/50 (R900430645) is a high-performance pressure relief valve designed for efficient pressure limiting within hydraulic systems. This sandwich plate valve is engineered to maintain system pressure with precision and reliability. The ZDB6VB2-4X/50 is comprised of a robust housing and one or two pressure valve cartridges, ensuring durable operation and adaptability to various circuit configurations. The valve's operation is straightforward: in its default state, the valve remains closed. Pressure from channel A acts upon the spool, while simultaneously being regulated by the spring-loaded side via a nozzle and influencing the pilot poppet through another nozzle. When the pressure surpasses the spring's set value, the pilot poppet activates, allowing hydraulic fluid to flow from the spool through nozzles and channel into channel T. This action results in a pressure drop that moves the spool to open the connection from A to T, thereby sustaining the preset pressure at the spring. Adjustment of system pressure can be tailored through different adjustment types provided with this model. Users can select from options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale for precise control over system pressures. Moreover, this model's design includes corrosion protection for longevity in harsh environments. The ZDB6VB2-4X/50 adheres to ISO porting patterns and offers flexibility with or without locating holes. It supports various pressure ratings and circuit options, equipped either with one or two pressure valve cartridges according to application needs. In summary, Bosch Rexroth's ZDB6VB2-4X/50 offers versatile applications for hydraulic systems requiring dependable pressure control. Its robust construction paired with customizable settings make it an essential component for maintaining optimal hydraulic performance across diverse operational requirements.
