The Rexroth R900500190 FD16PA21/B03V is a high-performance 2-way pressure compensator designed for precise hydraulic flow control. As a sandwich plate valve, it is engineered for easy installation in vertical stacking assemblies, fitting seamlessly with other size 16 components. Its primary function is to maintain a constant pressure drop across a metering orifice, such as a throttle valve, ensuring a consistent flow rate regardless of fluctuations in load pressure. This makes it an essential component in hydraulic systems requiring stable actuator speeds. The FD16PA21/B03V features a damping orifice for smooth operation and is built with FKM seals, making it compatible with a wide range of hydraulic fluids. Trust in Bosch Rexroth’s quality for reliable and efficient control of your hydraulic applications.
