Bosch Rexroth Z2FS-6-2-44 2QV Hydraulic Valve

Bosch Rexroth Z2FS-6-2-44/2QV is a twin throttle/check valve in Rexroth’s Z2FS family, designed for sandwich-plate installation in hydraulic systems. It meters flow with throttling in one direction while blocking reverse flow in the opposite direction, enabling precise, one-way control within compact manifolds. This Z2FS variant is commonly used in valve banks and automation circuits where space is at a premium and reliable flow regulation is required without separate check valves. The Z2FS-6-2-44/2QV designation identifies a specific configuration in the Z2FS lineup and is listed by distributors under part numbers such as R900481624, confirming its role as a double throttle/check valve. Typical applications include controlling actuator feed and return lines in machine tools, presses, and general automation equipment, where consistent metering improves motion repeatability and protects hydraulic components from unwanted surges. As with other Rexroth Z2FS components, it uses standard sandwich-plate sealing and is designed for compatibility with common industrial hydraulic fluids and operating within the temperature ranges specified for Rexroth hydraulic products. This model is suitable for integration into modular manifolds and custom valve blocks, delivering reliable flow control in tight-routing scenarios where two throttling elements provide balanced, predictable performance.
