DF Series Cast Iron 2/2-Way Solenoid Valve
- Direct Acting, Normally Closed
- Port Size: 1"–4" (flanged)
- Fluid Temperature: -5°C to 80°C (120℃ optional)
- Operating Pressure: 0–1.0MPa
- Media: air, water, oil, gas
DF series is a heavy-duty cast-iron flanged solenoid valve specifically designed for water supply and municipal engineering projects. The valve body is made of high-quality cast iron with a special anti-corrosion coating, providing excellent anti-rust and weather resistance. The valve meets IP65 protection standards, effectively resisting moisture and water spray, and maintaining stable performance in harsh environments.
- High-quality cast iron body with special anti-corrosion surface treatment, ensuring strong rust resistance and long service life in humid and corrosive environments.
- Standard flange connection provides stable installation and excellent sealing to prevent leakage
- Reinforced structure resists water hammer effects and pressure fluctuations, ensuring stable and reliable operation.
- Direct-acting design with low flow resistance, large flow capacity, and high tolerance for media impurities.
- Easy maintenance and operation with multiple flange sizes (1-4 in) and pressure options (0–1.0MPa) for flexible engineering applications
This cast iron solenoid valve is mainly used in environments that are continuously exposed to a humid environment or outdoors, such as:
- Water treatment plants
- Pumping stations
- Water transmission systems
- Municipal irrigation systems (e.g., drinking and wastewater)
- Firewater systems
- Industrial water supply systems
