Product details

1. Product Model Breakdown

• Brand: ATOS (Italian manufacturer, renowned in hydraulic/pneumatic systems)

• Model: DHA-0614/M

• DHA: Series code (typically indicates a direct-acting proportional directional control valve)

• 0614: Valve body size (e.g., port size 6mm, nominal flow rate 14L/min; specifics require reference to the manual)

• /M: Electrical interface type (e.g., integrated amplifier)

• Electrical Parameters: 24DC

• Supply voltage: 24V DC (standard for industrial automation)

• Performance Parameters: 25/BT

• 25: May indicate maximum operating pressure (250 bar) or nominal flow rate (verification needed)

• BT: Interface or feature identifier (e.g., panel-mounted, explosion-proof; refer to manual)

------

2. Core Functions

• Proportional Control: Continuously adjusts valve opening via electrical signals (e.g., 0-10V or 4-20mA) for linear flow/pressure regulation.

• Direct-Acting Design: Driven directly by electromagnetic force without pilot pressure, enabling fast response (<50ms).

• Integrated Amplifier(/M option): Built-in electronic amplifier simplifies external control circuits by directly accepting control signals.

3. Technical Specifications (Typical Values; Verify with Manual)

【表格】

Parameter Description

Nominal Flow Rate 14 L/min (for 6mm port size)

Max. Pressure 250 bar (25 may represent this value)

Supply Voltage 24V DC

Control Signal 0-10V DC or 4-20mA (confirm with manual)

Response Time <50ms (from signal input to valve action)

Leakage <0.1% of nominal flow (sealing performance)

Protection Rating IP65 (dust/water-resistant; BT may relate)

------

4. Selection Considerations

• Parameter Clarification: Confirm the exact meaning of "25/BT" in the ATOS manual (e.g., pressure rating, interface type).

• Environmental Adaptability: Select enhanced models for high-temperature/vibration environments.

• Compatibility: Ensure control signals (voltage/current) match PLC or controller requirements.

------

5. Applications

• Industrial Automation: Speed control for injection/clamping in plastic molding and die-casting machines.

• Construction Machinery: Precision motion regulation for excavator hydraulic arms.

• Aerospace: Pressure/flow control in aircraft actuator systems.

• Testing Equipment: Load simulation for material fatigue testing.
