Micro 1-Way Air Valve for Pressure Maintaining & Releasing

Short Description:

This valve features a 1-way, normally open (N.O.) design. This means the air passage remains open when the power is off, and the valve closes to block the airflow once energized.


  • Product Name: 1-Way Micro Normally Open Solenoid Valve
  • Rated Voltage: DC 3V / 3.7V / 6V / 12V
  • Weight: Approx. 10.0g
  • Exhaust Speed: < 4sec (from 300 to 15 mmHg in a 100cc tank)
  • Max Pressure: 40KPa (300mmHg)

    Engineering Integration Notes

    Mechanical Design and Layout

    Space-Optimized Structure: The ultra-compact rectangular shape is specifically designed for high-density PCB layouts and space-constrained housings.

    Optimized Air Port Connection: The integrated air nozzle is designed for a secure friction-fit connection with standard micro-tube tubing.

    Lightweight Integration: The ideal lightweight solenoid valve for handheld medical and beauty devices.

     

    Pneumatic Control Logic

    Default Airflow State: Ensures unobstructed airflow even when power is off.

    Dynamic Response Performance: Rapid state switching; instantly switches from an open flow path to a completely shut-off state upon power-up.

    System Integrity: High-precision internal seals minimize leakage and provide stable pressure support.

  • FAQ 1: Can this micro solenoid valve be customized for different voltages? How can I ensure it is compatible with my product’s circuit?

    A: Yes, we offer highly flexible voltage customization. Our PYF1-XA model standardly supports DC 3V, 3.7V, 6V, and 12V. Furthermore, our engineering team can adjust specific parameters—such as rated current or DC resistance—to match your circuit requirements. This ensures the valve achieves the perfect balance between power consumption and performance in your beauty devices or smart products.

    FAQ 2: How stable is the pressure-holding and exhaust performance in devices like smart pet feeders or medical equipment?

    A: It is exceptionally stable. Designed for high-precision pneumatic systems, this valve features excellent airtightness with a leakage rate of less than 3mmHg/min (tested at 300mmHg in a 100cc tank). It also offers rapid exhaust capabilities, dropping pressure from 300mmHg to 15mmHg in under 4 seconds. This ensures instant vacuum release for pet feeders and precise pressure relief for medical instruments.

    FAQ3: How durable is this product? Is it prone to damage in high-frequency use cases like massagers?

     A:You can rely on its durability. The PYF1-XA has passed rigorous life testing, maintaining performance for over 200,000 cycles (based on a 5s ON / 5s OFF cycle). Combined with its lightweight design (approx. 10.0g) and compact size (20×10×12mm), it is built to operate reliably even in portable massagers or beauty devices with high-frequency vibrations, significantly reducing your long-term maintenance costs.
