The DTF series solenoid valve is composed of a valve body and solenoid coils. It operates by using the solenoid coil to control the opening and closing of the valve, thereby regulating the flow or shutdown of refrigerant media in the system. These valves are primarily used in the refrigeration industry, including applications such as ice cream machines, ice makers, fried ice cream machines, and vending machines. The copper components can be customized in various shapes according to specific requirements.
Key technical specifications include:
- **Operating Voltage:** AC 220V/110V ±10%, 50-60Hz
- **Insulation Resistance:** ≥100MΩ
- **Electric Strength Test Pressure:** 4.5MPa
- **Air Tightness Test Pressure:** 2.0MPa
- **Maximum Pressure Difference:** Under 85% of rated voltage, 2.1MPa is normal
- **Internal Leakage:** Less than 50ml/min at P=2.1MPa
- **Fluid Temperature Range:** -20°C to 120°C
- **Ambient Humidity:** Below 95%
Here is a detailed table for different models:
| Model | Valve Diameter | Inlet | Outlet | Power Consumption | Action Type |
|-----------|----------------|-------|--------|-------------------|----------------------|
| DTF-1-2A | φ1.8mm | φ6mm | φ6mm | 6W | Direct action, open when powered |
| DTF-1-4A | φ4.0mm | φ6.4mm| φ6.4mm | 6W | Direct action, open when powered |
| DTF-1-6A | φ6.0mm | φ8mm | φ8mm | 6W | Direct action, open when powered |
| DTF-1-8A | φ8.0mm | φ10mm | φ10mm | 10W | Direct action, open when powered |
| DTF-2-2A | φ1.8mm | φ6mm | φ6mm | 6W | Direct action, close when powered |
**Q1: What is the warranty for the solenoid valves?**
A1: We offer a 1.5-year warranty on our valves. If any quality issues occur during this period due to our side, we will replace the product free of charge.
**Q2: What do NO and NC mean?**
A2: NO stands for Normally Open, meaning the valve remains open without power. When powered, it closes. NC stands for Normally Closed, meaning the valve remains closed without power. When powered, it opens.
**Q3: What is the recommended installation method for solenoid valves?**
A3: We recommend horizontal installation to extend the service life. However, vertical installation is also possible if required.
**Q4: Is there an affordable shipping option for importing to my country?**
A4: For small orders, express delivery is the best choice. For bulk orders, sea shipping is cost-effective but takes longer. For urgent orders, air shipping is suggested.
**Q5: Can we get custom-made products?**
A5: Yes, we specialize in custom manufacturing. Over 30% of our products are customized. We have successfully provided tailored solutions for customers from the USA, Norway, Australia, Germany, and other countries.
