ATOS QV-06 24 50 Hydraulic Flow Control Valve

ATOS QV-06 24 50 is a two-port, pressure-compensated hydraulic flow-control valve in ISO 4401 size 06 that provides precise, load-insensitive flow control in hydraulic circuits. It regulates up to 24 l/min with a defined minimum setting down to 50 cm3/min and resists system pressures up to 250 bar, making it well suited for metering fluid to hydraulic motors, cylinders, or test rigs where consistent flow governs speed and response. The QV-06 family uses standard NBR seals (with optional FKM or HNBR seals) and supports hydraulic fluids with typical cleanliness levels (ISO 4406 20/18/15) and a broad ambient temperature range (-30 °C to +70 °C standard; optional -40 °C to +70 °C in certain configurations). For the 24 l/min variant, the regulator presents a regulating Δp of about 8 bar, helping maintain stable flow despite supply-pressure fluctuations; maximum working pressure is 250 bar. The data sheet notes RoHS and REACH compliance, reflecting conformance to current European environmental and safety standards. In daily use, ATOS QV-06/24 valves are chosen when a compact, robust solution is needed to decouple downstream flow from upstream pressure, enabling reliable cylinder speeds, controlled actuation, and repeatable test results across a wide range of hydraulic systems.
