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.

Features

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

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
