SMC SY3140-5FU-Q Solenoid Valve (SY31405FUQ)
1. Product Overview
The SMC SY3140-5FU-Q is a 2-position, 5-port single solenoid valve of the SY3000 series, designed for efficient pneumatic control in industrial automation systems. It adopts an internal pilot design, a low-power DC24V coil, and a plug-in sub-base piping configuration, along with a direct outlet (FU-type) wiring for simplified installation. With an operating pressure range of 0.15–0.7 MPa, it is ideal for controlling double-acting cylinders in electronics manufacturing, automotive assembly, and packaging machinery. The valve provides rapid response (12–15 ms), reliable sealing, and maintenance-free operation, while its non-locking push-type manual override enables on-site debugging without power. Its compact zinc alloy body and flexible mounting options (sub-base or direct piping) make it suitable for space-constrained automation setups, ensuring seamless integration and long-term reliability.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Pneumatic Actuator Control | 5-port (P, A, B, R1, R2) setup switches airflow to double-acting cylinders, enabling bidirectional motion in pick-and-place, assembly, and transfer tasks. |
| Manual Override | Non-locking push-type plunger allows manual actuation for system debugging without power, automatically resetting to the normal state post-operation. |
| Status Feedback | Built-in LED indicator and surge protection circuit provide real-time coil status monitoring, supporting PLC safety interlocks and troubleshooting. |
| Low-Power Operation | 0.1W power-saving coil reduces energy consumption by approximately 75% compared to standard 0.4W valves, ideal for high-cycle applications and energy-efficient systems. |
| Rapid Airflow Switching | Internal pilot design and elastic sealing deliver a 12–15 ms response time and a maximum operating frequency of 10 Hz, meeting the demands of high-speed automation cycles. |
| Flexible Mounting | Supports sub-base installation and 3/5-port mixed mounting, allowing for customized system layouts and simplified integration into dense automation setups. |
3. Technical Features
- Internal Pilot Operation: Utilizes the system’s supply pressure for pilot actuation, eliminating external pilot lines and simplifying installation and piping complexity.
- Low-Power Solenoid Coil: 0.1W power consumption (DC24V) minimizes energy costs and heat generation, suitable for battery-powered or energy-efficient automation systems.
- Durable Construction: Die-cast zinc alloy valve body with corrosion-resistant coating; NBR rubber seals ensure airtight performance and a service life of ≥50 million cycles.
- IP65 Protection Rating: Dust-tight and water-resistant design (for the connector area) protects internal components from industrial contaminants, ensuring stable operation in harsh environments.
- Plug-in Sub-base Piping: Plug-in sub-base design for P, A, B, R1, R2 ports enables quick and secure piping connections, reducing maintenance downtime.
- Lubrication-Free Compatibility: Pre-lubricated internal components support oil-free pneumatic systems, avoiding contamination of sensitive workpieces in clean manufacturing processes.
- RoHS Compliance: Meets international environmental standards, free of restricted hazardous substances (e.g., lead, mercury), suitable for eco-friendly production facilities.
- High Sealing Performance: Elastic seal structure ensures minimal leakage (≤0.1 cm³/min at 0.7 MPa), maintaining system pressure stability and reducing compressed air waste.
