A hydraulic valve that controls the direction of fluid flow in a hydraulic system.
Technical details and manufacturing context for Directional Control Valve
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Nominal Size | 6–32 mm | Determines flow capacity and port size.ISO 4411 |
| Max Flow Rate | 40–300 L/min | Exceeding may cause cavitation and pressure drop.ISO 10770-1 |
| Operating Pressure | 1.0–35 MPa | Below 1.0 MPa seat load insufficient; above 35 MPa seal failure. |
| Leakage Rate | ≤0.1 mL/min | Higher leakage indicates internal wear.ISO 6403 |
| Response Time | 10–50 ms | Faster for servo valves; slower for manual.ISO 10770-1 |
| Coil Voltage | 12–24 V DC | AC versions available; tolerance ±10%.IEC 60038 |
| Coil Power | 20–40 W | Affects heat generation and duty cycle.IEC 60034-1 |
| Operating Temperature | -20–80 °C | Outside range seals and fluid degrade.ISO 4413 |
| IP Rating | IP54–IP65 | Higher for outdoor or washdown.IEC 60529 |
| Body Material | HT250–QT450 | Ductile iron for higher pressure.GB/T 9439 |
| Weight | 1.5–25 kg | Depends on size and configuration. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It directs hydraulic fluid flow to specific actuators, controlling the direction of movement (e.g., extend/retract cylinders, rotate motors) or holding a position by blocking flow paths.
Typical ranges are 1.0–35 MPa for operating pressure and 40–300 L/min for maximum flow rate, but these must be confirmed for the specific model and application.
Common materials include carbon steel, stainless steel, and brass. The body material grade may vary, such as HT250 or QT450, depending on pressure requirements.
Check the valve's datasheet for parameters like nominal size, flow rate, pressure, leakage, response time, and IP rating. Always confirm these values and applicable standards with the legal manufacturer or supplier.
