VQC2B01N-51: Pilot-Operated 5-Port Solenoid Valve, High-Integration Control Core with Plug-In Unit

Product Positioning
The VQC2B01N-51 is a pilot-operated 5-port solenoid valve from the SMC VCQ2000 series, featuring a plug-in unit and base mounted design. This series focuses on space saving and volume reduction as its core advantages, enabling quick valve replacement through a screwless single-clamping structure. The built-in one-touch fittings simplify piping work, and the slide-lock type manual operation facilitates on-site commissioning. This product is widely used in packaging machinery, electronic assembly, medical devices, and various general automation production lines requiring high-density integrated pneumatic control.

Core Highlights: Plug-In Structure, Quick Replacement, Negative Common Specification

• Plug-In Unit Design, Easy Maintenance
  • Adopts a plug-in unit structure where the valve body can be directly inserted into the base, completing electrical and pneumatic connections simultaneously.
  • The screwless single-clamping structure makes valve replacement extremely simple and fast, significantly reducing equipment downtime and improving maintenance efficiency.
• Base Mounted Type, Saves Space
  • Uses base mounted method,集中布置气路接口 on the base plate, facilitating integration onto manifold blocks to form high-density valve groups, simplifying external piping and saving installation space.
• Negative Common Specification, Flexible Control
  • “N” in the model represents the negative common specification, where the common terminal is negative (0V), suitable for specific electrical control system wiring requirements.
  • Equipped with an indicator light and surge voltage protection circuit. The LED indicator shows the operating status in real-time, and the surge protection circuit effectively safeguards the control system from voltage spikes.
• 5-Port, 4-Position Function, Dual Valve Combination
  • Valve function code “51” represents 4-position (N.O. + N.O.), i.e., a combination of two normally open ports, enabling special control requirements for actuators like double-acting cylinders.
  • De-energized state is self-resetting (spring return).
• Single Solenoid Design, Wide Operating Condition Adaptability
  • Uses single solenoid structure, operation type is solenoid valve/pilot valve/spring.
  • Coil voltage DC24V, power consumption 1W.
  • Operating pressure range 0.15 to 0.7 MPa, working temperature range -10 to +50°C.
  • Seal type is soft seal.
• Built-in One-Touch Fittings, Convenient Piping
  • Built-in one-touch fittings in the valve body, suitable for quick connection of nylon, polyurethane tubing without requiring additional tools.
• Convenient Manual Operation, Trouble-Free Commissioning
  • Manual operation is non-locking push type (tool-operated), facilitating on-site commissioning, fault diagnosis, and emergency manual control during power outages.
