DF Solenoid Valve for LiquidsOverview

The DF Series Pilot Operated Liquid Solenoid Valve is a high-performance electromagnetically driven valve specifically engineered for medium-to-large scale industrial fluid pipeline control systems. Boasting a highly comprehensive range of specifications, the series covers nominal diameters from DN15 to DN200, fully supporting both high-precision threaded and heavy-duty flanged connections for seamless integration into high-standard industrial piping networks. The valve delivers exceptional opening/closing responsiveness and premium sealing reliability within a nominal pressure rating of 0.8 MPa. Available in dense hot forged brass or high-strength cast iron, the valve bodies are universally compatible with water, liquids, neutral gases, and low-to-medium viscosity industrial oils (≤ 4°E). Utilizing an advanced pilot-operated design, this series exhibits low power consumption, high flow coefficient, and outstanding anti-water hammer characteristics, making it an ideal control component for industrial automation and water treatment applications.

DF Solenoid Valve for LiquidsCharacteristic

Expansive Bore Size & Dual Connection Options: Spanning from DN15 to DN200, the series provides high-precision threaded options for small-bore piping and heavy-duty flanged options for large-bore systems, comprehensively satisfying diverse industrial needs from terminal precision control to main header distribution.

Pilot-Operated Energy-Saving Design: Utilizing advanced pilot diaphragm/piston balancing technology, the valve harnesses the pressure of the fluid medium itself to facilitate actuation. This significantly reduces the power consumption of the solenoid coil while ensuring swift, clean open/close strokes under high velocity and large flow conditions.

Premium Materials & Robust Pressure Resistance: Constructed from dense hot forged brass or premium cast iron, the structural integrity of the valve body has undergone strict flow-field optimization. It guarantees zero deformation and zero external leakage at a working pressure of 0.8 MPa, offering superior fatigue strength.

Versatile Media Compatibility: Engineered with specially modified internal seals, the valve not only provides long-term, zero-leakage isolation for water and gases but also effortlessly manages various industrial oil products with viscosities up to 4°E.
