SMC SY3140-5FU-Q Solenoid Valve (SY31405FUQ)<\/h1>\n
<\/div>\n

1. Product Overview<\/h2>\n
<\/div>\n
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\u20130.7 MPa, it is ideal for controlling double-acting cylinders in electronics manufacturing, automotive assembly, and packaging machinery. The valve provides rapid response (12\u201315 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.<\/div>\n

<\/div>\n
\n
\n\n\n\n\n\n\n\n\n\n\n
Function<\/th>\nDetailed Description<\/th>\n<\/tr>\n<\/thead>\n
Pneumatic Actuator Control<\/td>\n5-port (P, A, B, R1, R2) setup switches airflow to double-acting cylinders, enabling bidirectional motion in pick-and-place, assembly, and transfer tasks.<\/td>\n<\/tr>\n
Manual Override<\/td>\nNon-locking push-type plunger allows manual actuation for system debugging without power, automatically resetting to the normal state post-operation.<\/td>\n<\/tr>\n
Status Feedback<\/td>\nBuilt-in LED indicator and surge protection circuit provide real-time coil status monitoring, supporting PLC safety interlocks and troubleshooting.<\/td>\n<\/tr>\n
Low-Power Operation<\/td>\n0.1W power-saving coil reduces energy consumption by approximately 75% compared to standard 0.4W valves, ideal for high-cycle applications and energy-efficient systems.<\/td>\n<\/tr>\n
Rapid Airflow Switching<\/td>\nInternal pilot design and elastic sealing deliver a 12\u201315 ms response time and a maximum operating frequency of 10 Hz, meeting the demands of high-speed automation cycles.<\/td>\n<\/tr>\n
Flexible Mounting<\/td>\nSupports sub-base installation and 3\/5-port mixed mounting, allowing for customized system layouts and simplified integration into dense automation setups.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

3. Technical Features<\/h2>\n
<\/div>\n
    \n
  1. Internal Pilot Operation<\/strong>: Utilizes the system’s supply pressure for pilot actuation, eliminating external pilot lines and simplifying installation and piping complexity.<\/li>\n
  2. Low-Power Solenoid Coil<\/strong>: 0.1W power consumption (DC24V) minimizes energy costs and heat generation, suitable for battery-powered or energy-efficient automation systems.<\/li>\n
  3. Durable Construction<\/strong>: Die-cast zinc alloy valve body with corrosion-resistant coating; NBR rubber seals ensure airtight performance and a service life of \u226550 million cycles.<\/li>\n
  4. IP65 Protection Rating<\/strong>: Dust-tight and water-resistant design (for the connector area) protects internal components from industrial contaminants, ensuring stable operation in harsh environments.<\/li>\n
  5. Plug-in Sub-base Piping<\/strong>: Plug-in sub-base design for P, A, B, R1, R2 ports enables quick and secure piping connections, reducing maintenance downtime.<\/li>\n
  6. Lubrication-Free Compatibility<\/strong>: Pre-lubricated internal components support oil-free pneumatic systems, avoiding contamination of sensitive workpieces in clean manufacturing processes.<\/li>\n
  7. RoHS Compliance<\/strong>: Meets international environmental standards, free of restricted hazardous substances (e.g., lead, mercury), suitable for eco-friendly production facilities.<\/li>\n
  8. High Sealing Performance<\/strong>: Elastic seal structure ensures minimal leakage (\u22640.1 cm\u00b3\/min at 0.7 MPa), maintaining system pressure stability and reducing compressed air waste.<\/li>\n<\/ol>\n
