Small Electric Water Valve: Flow Control 12V/24V | Pinmotor

1. Can this valve handle liquids other than water?

Direct Answer: While optimized for water, the brass and EPDM/Nylon materials can handle neutral, non-corrosive fluids.

Details: The PYF3-XG is specifically designed for water-based media. If your application involves mild chemicals or food-grade liquids (like milk or alcohol), please verify chemical compatibility. The brass body is highly resistant to oxidation, but for acidic fluids, we recommend our specialized PTFE-lined models. Pincheng Motor provides custom material sourcing for orders exceeding 500 units to ensure long-term chemical resistance and prevent seal failure.

2. What is the power consumption of the 12V and 24V models?

Direct Answer: The 12V model operates at 2.88W, while the 24V model draws 5.76W.

Details: Low power consumption is a core design feature of the PYF3-XG. The 12V version draws approximately 240mA, making it compatible with most standard PCB drivers and battery-operated systems. This efficiency minimizes thermal emission, which is vital for compact medical devices where heat can affect sensitive reagents or electronic components. Our engineering team has optimized the coil resistance (50-100Ω) to balance magnetic force with energy efficiency.

3. Is this valve “Normally Open” or “Normally Closed”?

Direct Answer: The standard PYF3-XG is a “Normally Closed” (NC) solenoid valve.

Details: A “Normally Closed” configuration means the valve remains shut when no power is applied, preventing fluid flow during power outages or system shutdowns—a critical safety feature for water dispensers and appliances to prevent flooding. Upon receiving a DC signal, the solenoid lifts the plunger in ≤0.5 seconds to allow flow. If your project requires a “Normally Open” (NO) configuration for continuous flow systems, Pincheng offers OEM customization to meet your specific logic requirements.

4. How does the IP65 rating benefit my application?

Direct Answer: The IP65 rating ensures the valve is protected against dust ingress and low-pressure water jets from any direction.

Details: In environments like industrial kitchens (dishwashers) or outdoor irrigation, moisture is a constant threat to electrical components. The IP65-rated housing protects the internal copper coils from short-circuiting due to humidity or accidental splashes. This rating, verified through IEC 60529 testing, guarantees that the PYF3-XG maintains electrical integrity in 30% to 85% RH (Relative Humidity) conditions, significantly reducing maintenance costs and downtime.

5. What is the maximum pressure this micro valve can withstand?

Direct Answer: The valve is rated for a maximum water pressure of 14.5 PSI (100 kPa). Details: Designed for low-to-medium pressure systems, the PYF3-XG handles up to 14.5 PSI with a leakage-free guarantee. During our quality assurance process, each unit is tested in a 100cc tank to ensure leakage remains below 10 mmHg/min. This makes it ideal for gravity-fed systems or small pump-driven loops. If your system experiences higher pressure spikes, we recommend installing a pressure regulator or consulting our engineering team for a high-pressure reinforced brass variant.
