Pincheng Factory presents the PYF2-XC, a high-performance 3.7v dc micro solenoid valve 2 way engineered for precision air control in compact electronic devices. This normally closed valve excels as a reliable air valve for blood pressure monitor systems, providing rapid exhaust functionality with a response speed under 4 seconds (300mmHg to 15mmHg in 500cc tank). Its compact dimensions (15mm typical) and lightweight design (16.5g) make it ideal for space-constrained medical and personal care applications.
Operating as a true Low Power Consumption Micro Solenoid Valve, it requires only 1.37W at 3.7V DC (370mA), making it perfectly suited for battery-powered portable devices. The valve demonstrates exceptional sealing performance with leakage under 3mmHg/min and withstands pressures up to 40KPa, ensuring reliable operation in critical medical and wellness equipment. With an operational lifespan exceeding 200,000 cycles and compatibility with various DC voltages, this robust component serves as an optimal solution for precision air release valves in sphygmomanometers, compact exhaust valves for adult products, and efficient pressure control valves in massage equipment and essential oil diffusers.

Description
Pincheng Factory presents the PYF2-XC, a high-precision miniature Mini solenoid valve for medical/personal care equipment (e.g., blood pressure monitors). This advanced air valve delivers top pneumatic control with rapid exhaust (<4s response) for precise pressure management. Its 15mm size, 16.5g weight makes it ideal for space-constrained medical/portable pneumatic systems, where reliability and size matter.
As a Low Power Consumption Micro Solenoid Valve, the PYF2-XC runs at 1.37W (3.7V DC), perfect for battery-powered medical gear and energy-efficient pneumatic controls. Normally closed for fail-safe use, its 200,000-cycle lifespan ensures long-term reliability for high-frequency uses (sphygmomanometers, adult products, massage devices). It has superior sealing (<3mmHg/min leakage) and handles max 40KPa, ensuring stability in precision pressure release/medical air control systems.

How To Choose The Right Micro Solenoid Air Valve For Blood Pressure Monitor Applications?
In designing and manufacturing blood pressure monitors, choosing the right micro electromagnetic air valve is critical-it directly determines the device's "vital signs." Evaluate valves from 5 key dimensions, using Pincheng Factory's PYF2-XC as an example.
Precision & Speed
It needs fast, smooth air release for accurate pressure control. PYF2-XC reduces pressure in a 500cc cavity from 300mmHg to 15mmHg in 4 seconds, capturing reliable pulse waves for systolic/diastolic calculations.
Sealing Performance
Leakage ruins readings. PYF2-XC's normally closed design has a leakage rate <3mmHg/min at 300mmHg, keeping cuff pressure stable during measurement.
Energy Efficiency
For portable, battery-powered monitors, PYF2-XC offers 3V-12V options; the 3.7V version uses only 1.37W, extending battery life.
Durability
Withstanding over 200,000 on-off cycles, it supports 4 daily uses for over 130 years, ensuring long-term reliability.
Size & Integration
Its 15mm size and 16.5g weight fit compact monitor designs, avoiding miniaturization bottlenecks.
