Z2FGM6T2-2X/2QV

The Z2FGM6T2-2X/2QV valve is produced by Bosch Rexroth as part of the ZXFG Throttle Valves series. It serves to meter fluid and adjust actuator speed in hydraulic automation. The valve is built as a throttle in sandwich plate form so it can be stacked between sub-plates without extra piping. Its nominal size is 6 (NG6), matching compact manifolds used in small to medium machinery. A porting pattern of ISO 4401-03-02-0-05 aligns the plate openings with standard sub-plates to simplify installation. Two separate throttling functions are available on ports A and B, allowing symmetrical flow control for bidirectional cylinders. Flow can be metered in both directions, enabling consistent speed adjustment during extension and retraction. A maximum flow capacity of 70 l/min supports moderate actuator demands while avoiding excessive pressure drop. The unit weighs 1.3 kg, light enough for stacking without overloading manifold hardware.

The valve withstands a maximum operating pressure of 315 bar so it can be placed downstream of high-pressure pumps without risk of deformation. Mineral oil of the HL or HLP grades specified in DIN 51524 is the approved hydraulic fluid, ensuring compatibility with common industrial power units. A cleanliness level of ISO 4406 20/18/15 is required to prevent erosion of the throttling gaps and to maintain predictable metering. FKM seals are installed to tolerate elevated oil temperatures and resist chemical degradation from the recommended fluids. Meeting this contamination limit guides filter selection during commissioning and service. With these fluid and sealing requirements met, the valve keeps leakage low and holds set flow rates over long service intervals.
