VQ4100R-41: Pilot-operated 5-Port Solenoid Valve, High-Rigidity, Long-Life Integrated Control Core

Product Positioning
The VQ4100R-41 is a pilot-operated 5-port solenoid valve from SMC’s VQ4000 series. It features a 2-position single solenoid, sub-plate base piping type design, and utilizes a metal seal sealing method. This series is distinguished by its compact size, high flow capacity, and long service life, achieving a 42% reduction in installation volume and a 26% reduction in mounting area compared to conventional products. Its excellent flow characteristics and high reliability make it an ideal choice for automotive manufacturing, packaging machinery, electronic assembly, and various automation lines requiring the driving of medium to large cylinders (up to Ø160mm bore).

Core Highlights: Compact & High Flow Capacity, Long Life & High Reliability

• Compact Design, High Flow Output
  • Compared to traditional products, installation volume is reduced by 42% and mounting area by 26%, significantly saving space while providing an excellent flow capacity with a Cv value of 1.5.
  • Can drive cylinders with a maximum bore size of Ø160mm, meeting the driving needs of medium to large loads.
• Metal Seal, Long-Life Assurance
  • Employs a metal seal structure, featuring precision metal-to-metal fit between the spool and sleeve, eliminating the need for rubber seals.
  • Service life exceeds 100 million cycles (under SMC test conditions), significantly enhancing long-term operational reliability and maintenance intervals.
• External Pilot Type, Vacuum Compatible
  • The “R” in the model denotes external pilot type, with a minimum operating pressure of 0.15 MPa and a maximum operating pressure of 1.0 MPa.
  • The external pilot design makes it suitable for vacuum environments or applications with unstable low-pressure air supplies, broadening its application range.
• Fast Response, Reliable Operation
  • Response time is only 20 ms (standard type at 0.5 MPa), meeting medium to high-speed automation cycle requirements.
  • Excellent impact and vibration resistance ensure reliable operation in vibrating environments.
• IP65 High Protection Class, Strong Environmental Adaptability
  • Protection rating is IP65 (dust-tight and protected against jetting water), offering excellent dust and water resistance suitable for harsh general industrial environments.
• Rich Optional Configurations, Flexible Adaptation
  • Depending on the specific model suffix, coils with standard power consumption (0.95W) or low power consumption (0.4W) can be configured to meet energy-saving needs.
  • Manual override options include non-locking push-turn type (requiring tool), facilitating on-site adjustment and emergency manual control.
  • Port threads available in Rc, G, NPT, NPTF, etc., adapting to different regional standards.
