Product Description

Normally Closed Solenoid Valve For Breast Pumps

Stable Suction Control for Breast Pump Systems

Breast pumps need steady suction switching to keep the pumping rhythm smooth and comfortable. If the airflow changes too suddenly or pressure becomes unstable, the user experience can feel uncomfortable during long use periods. The Normally Closed Solenoid Valve For Breast Pumps was designed for compact pumping systems that require cleaner pressure control and faster airflow response.

Parameter	Specification
Model No.	MXV1520-01B
Rated Voltage	DC3.7V
Air Tightness	<3.0mmHg/min
Exhaust Speed	<3s
DC Resistance	9±10%Ω
Operating Temperature Range	0~50℃

Using a normally closed structure, the valve stays sealed when power is off, helping maintain more stable suction control inside portable pumping equipment.As a Normally Closed Solenoid Valve, it works especially well in products that need repeated pressure switching during continuous operation.

Faster Exhaust Helps Create Smoother Pumping Rhythm

Breast pumps constantly cycle between suction and pressure release. Slow airflow discharge often causes delayed rhythm changes and weaker pumping consistency.

The MXV1520-01B 12 volt solenoid valve normally closed keeps exhaust speed below 3 seconds, helping pressure release respond faster during repeated cycles. A tightness level below 3.0 mmHg/min helps reduce leakage.

For portable healthcare products and maternal care devices, this type of airflow consistency helps create a softer and more natural pumping experience.As an electric solenoid, it supports repeated switching performance in compact electronic systems.

Compact Size Makes Portable Device Design Easier

Modern breast pumps are becoming smaller, lighter, and easier to carry. Large airflow components usually create unnecessary space limitations during assembly.

The MXV1520-01B 2 solenoid valve normally closed keeps a compact structure while maintaining stable operation within a 0~50℃ working environment. The smaller design helps manufacturers improve internal layout flexibility for portable healthcare products and wearable pumping devices.
