Product details

1. Model Breakdown

D5-02-3C4-A25-10is a directional control valve model from RISUNY (or a similar brand). The meaning of each segment is as follows:

• D5: Valve series or size code, typically indicating port size or mounting dimensions (e.g., DN5 or 5mm bore).

• 02: Function code, possibly denoting valve positions (e.g., 2-position) or control method (e.g., solenoid-operated).

• 3C4:

• 3: Spool design or neutral position function (e.g., "3" in a 3-position 4-way valve may represent a closed-center neutral position).

• C4: Port configuration or seal material (e.g., Type C port, NBR rubber seals).

• A25:

• A: Voltage type (e.g., AC).

• 25: Rated voltage value (e.g., 24V, 110V, or 220V; confirm with product specifications).

• 10: May indicate flow coefficient, pressure rating, or series version number.

Note: Naming conventions may vary by manufacturer. Refer to RISUNY’s official documentation for confirmation.

2. Technical Specifications (Typical Values, Subject to Actual Product)

【表格】

Parameter Description

Valve Type Solenoid-operated directional control valve (e.g., 2-position 3-way or 3-position 4-way)

Port Size DN5 (5mm) or similar small-bore design

Control Method Solenoid-driven (single or double solenoid)

Voltage AC24V, AC110V, or AC220V (confirm "A25" value in the model)

Pressure Range 0.1–1.0 MPa (low-pressure applications, e.g., pneumatic or small hydraulic systems)

Flow Range 0.5–5 L/min (low-flow scenarios)

Seal Material NBR (Nitrile Butadiene Rubber, for mineral oil or air) or FKM (Fluorocarbon, for high-temperature/chemical resistance)

Ambient Temperature -10°C to +60°C (standard industrial environment)

Protection Rating IP65 (dust-tight and water-resistant, suitable for general industrial use)

------

3. Applications

• Pneumatic Systems: Control of cylinders, pneumatic grippers, or vacuum suction cups.

• Small Hydraulic Systems: Machine tool clamping, auxiliary actions in injection molding machines.

• Automation Equipment: End-effector control in robots, workstation switching in assembly lines.

• Laboratory Equipment: Precision fluid control in medical devices or analytical instruments.

------

4. Selection Considerations

1. Valve Type Confirmation:

• Is it a 2-position 3-way (2/3) or 3-position 4-way (3/4) valve? Does the neutral position (e.g., O-type, H-type) meet system requirements?

2. Voltage Compatibility:

• Ensure the solenoid coil voltage matches the control system (e.g., AC24V requires a transformer).

3. Port Size Matching:

• Thread interfaces (e.g., G1/8, M5) must align with piping.

4. Media Compatibility:

• For hydraulic oil, confirm seal material compatibility; for water-based media, opt for stainless steel valves.

5. Response Time:

• Small valves typically respond quickly (<50ms), but verify if they meet equipment cycle time demands.
