Engineering Integration Notes

1. Electrical Integration & Power Management

Voltage Selection: This series offers three distinct rated voltage options: DC 6V, DC 12V, and DC 24V. Engineers should select the model that matches their system's power rail to ensure optimal performance.
Power Consumption: Depending on the voltage, the power draw ranges from 1.8 W (at 6V) to 3.36 W (at 24V). Ensure the driving circuit (e.g., MOSFET or Relay) can handle the corresponding rated current, which ranges from 140mA to 300mA.
Wiring Interface: The valve comes pre-equipped with UL1007 26AWG lead wires ($200\pm10$ mm length) and a 2.54mm buckled terminal for secure, plug-and-play connection to PCBs.

2. Pneumatic Performance & Circuit Design

Rapid Exhaust Capability: Engineered for speed, it can exhaust a 500cc tank from 300mmHg to 15mmHg in less than 2 seconds. This is critical for simulating realistic massage rhythms in foot massagers.
Pressure & Sealing: The maximum rated pressure is 40KPa (300mmHg). The unit maintains high-precision sealing with a leakage rate of less than 3mmHg/min.

Next:

1. How fast can thisvalve deflate air from my device?
A: Speed is one of our biggest strengths. This three-way solenoid valve is built for rapid deflation, meaning it can exhaust air from a standard massager airbag in less than 2 seconds.

2. Will this valve hold up over years of daily use?
A:Absolutely. We know reliability is key for medical monitoring and foot massagers. Our exhaust valves are tested to last for over 200,000 cycles.

3. Can I get a version that fits my specific power requirements?
A:Yes, we specialize in factory-direct customization. While we offer standard DC 6V, 12V, and 24V options, Pinmotor can adjust the lead wires, terminals, and other electrical specs to perfectly match your portable beauty instruments or specialized equipment.
