DC Motorized Ball Valve Low Flow Resistance Auto Control
DN40 DC12V/24V Electric Ball Valve – full port with low flow resistance, available in 2‑wire/5‑wire versions, supports PLC automation, specifically designed for outdoor DC systems in irrigation, HVAC, and water treatment, with manual override.
Description
1. Operating Principle & Core Advantages
This DC motorized ball valve is powered by a low‑consumption DC actuator that responds to DC12V or DC24V signals to drive 90° on/off operation. It is ideal for outdoor automation systems without AC power supply. The body features a full port motorized ball valve design with no internal bore reduction, ensuring extremely low flow resistance and significantly reducing pump energy consumption.
Two wiring options are available: 2 wire motorized ball valve and 5 wire motorized ball valve—the 5‑wire version provides valve position feedback for seamless integration with PLC controllers and IoT‑based irrigation systems.
A manual override is provided for emergency manual operation during power outages, ensuring system reliability. The valve body is available in brass or 304 stainless steel, offering corrosion resistance for media such as irrigation water, HVAC chilled water, and pure water.

3. Key Application Industries
This valve is well suited for outdoor smart irrigation, photovoltaic‑powered water supply systems, remote water treatment units, vehicle‑mounted fluid equipment, HVAC motorized ball valve systems in split HVAC units, and small‑scale automated chemical pipelines. The DC‑powered version is preferred for off‑grid sites, eliminating the need for additional transformers.
4. Overseas Field Project Example
A large‑scale landscape irrigation farm in Central California (4125 W Shaw Ave, Fresno, CA 93701) deployed this 1 1/2″ DC motorized ball valve across its entire zoning irrigation network. With no AC power available in the fields, the system relies entirely on solar‑powered DC24V valves, which work in tandem with soil moisture sensors for fully automated water control.
The full‑port design significantly reduced pipeline pressure losses, cutting pump load by 22%. The entire automation system has operated reliably for 18 months with no leakage or motor burn‑out issues, establishing this valve as a benchmark component for photovoltaic‑driven irrigation in North America.
5. Advantages for Overseas Procurement
DC power eliminates the need for external transformers, reducing accessory costs for overseas off‑grid engineering projects. The stainless steel body resists sediment and corrosion, while the IP67 waterproof option ensures reliable performance in open‑air rain conditions.
CE certification is available, and we support custom configurations for normally open/normally closed operation and feedback signal types, catering to the bulk procurement needs of outdoor automation projects in Europe, America, and Australia.
