3-Way Solenoid Valve for Oximeter Equipment

Stable Air Switching Helps Improve Measurement Accuracy

Oximeter equipment and portable medical monitoring devices often rely on accurate pneumatic control during pressure adjustment and airflow switching. If the valve response becomes unstable, the measurement process can easily slow down or lose consistency.

Parameter	Specification
Model No.	MXV1220-01
Rated Voltage	DC3.0V / DC3.7~12V (Series)
Rated Current	60±10% mA
Rated Power	1.8±10% W / 0.34W (Reference)
Air Tightness	＜3.0mmHg/min
Exhaust Speed	＜5s (300mmHg→15mmHg, 100cc)
Structure	Normally Open, One-way
Rated Load	300mmHg
Air Circuit Status	Port 1-2 closed when energized, open when de-energized

The 3-Way Solenoid Valve for Oximeter Equipment is designed for compact medical pneumatic systems that require fast exhaust response and reliable air circuit control. The MXV1220-01 small solenoid valvekeeps air tightness below 3.0mmHg/min, helping maintain more stable pressure control during repeated operating cycles.

Low Voltage Design Supports Portable Medical Devices

Battery-powered healthcare products need pneumatic components with lower power consumption and stable low-voltage operation. Larger valves often create unnecessary power load and increase heat during continuous use.

Normally Open Solenoid Valve For Pulse Oximeter

The MXV1220-01 Normally Open Solenoid Valve supports DC3.0V operation and is also compatible with DC3.7~12V series specifications, giving engineers more flexibility during product development. With rated current controlled at only 60±10% mA, the valve helps reduce power usage while maintaining reliable switching performance.

This Low voltage three-way Solenoid Valve is commonly used in:

Oximeter equipment

Portable diagnostic devices

Pneumatic healthcare systems

Smart monitoring instruments

Compact medical control systems

Fast Exhaust Performance Improves System Response

In medical airflow systems, slow exhaust speed can affect pressure recovery and reduce equipment response efficiency. Fast switching performance becomes especially important in repeated testing environments.

The MXV1220-01 electric solenoid keeps exhaust speed below 5 seconds under 300mmHg to 15mmHg testing conditions with 100cc volume. This helps the pneumatic system recover pressure more smoothly during repeated operation.

Normally Open Structure Simplifies Airflow Management

Different medical devices require different airflow logic during standby and working conditions. A normally open structure helps simplify pneumatic pathway design and improves default airflow stability.

The MXV1220-01 normally open solenoid Valve uses a one-way Normally Open structure. Port 1-2 remains open when de-energized and closes after energizing, allowing stable airflow switching inside compact medical systems.
