Application Focus: Pneumatic Circuit in Robotic Cleaners & Smart Appliances
Instant Pressure Relief in Cleaning Docks
With an exhaust speed under 3.0 seconds (100cc tank), the SC0519AVG provides rapid pneumatic venting and bypass switching during dust container emptying, auto-cleaning mop pressure release, and sealed system protection.
Compact Footprint for High-Density Layouts
Standing only 14.3mm high with a core body length of 18.6mm, this micro solenoid valve is ideal for tightly packaged robotic vacuum internal chassis and lightweight wearable massagers.
200,000-Cycle Endurance Reliability
Tested under rigorous 12s on / 5s off cyclic operations, the precision electromagnetic core and wear-resistant sealing structure guarantee zero-sticking performance across extended product service lifecycles.
Flexible Multi-Voltage Architecture
Available in 3V, 6V, and 12V coil ratings. Easily integrated with lithium battery management systems (BMS) and standard robotic vacuum mainboards without additional voltage buck-boost circuits.
Pneumatic Port Definition & Working Principle
- Common Port (Port 1): Directly connects to the working circuit, air chamber, or sensor port.
- Normally Open Port (Port 2): Connected to Port 1 when the solenoid is de-energized, allowing free airflow or pressure retention.
- Exhaust / Diverter Port (Port 3): Opens instantaneously when the coil is energized (3V/6V/12V), venting air or rerouting pressure to the atmosphere.
* Custom port orientations, barb diameters, and customized mounting brackets are available upon request.
