The Bosch Rexroth R900440565 Z2FS6B2-46/2QV is a high-performance double throttle/check valve designed for precise flow control in hydraulic systems. As a sandwich plate valve of size 6, it is engineered for vertical stacking assemblies, conforming to ISO 4401 porting patterns. This model provides meter-out control, allowing for the fine adjustment of actuator speed by limiting the flow leaving the actuator. The valve features two adjustable throttle elements, enabling independent control for two ports. This specific version is configured without a check valve in channel A and is equipped with durable FKM seals for compatibility with a wide range of hydraulic fluids. Its robust construction ensures reliable operation under high pressure, making it an ideal choice for industrial applications requiring accurate and repeatable speed regulation.
